Java Binary Operators
In this article, we are going to discuss about the binary operators in Java and their operations. Also, an example program will be discussed along with the operations. These are very important for clearing the coding test in interview point of view.
Binary Operators
An operator known as a binary operator that manipulates two operands to get a result. Operators offer a simple way to evaluate integer data or character strings and are specified by special elements or by keywords.
The binary operators will be shown as follows:
A operator B
Where A = Operand1 operator operator2
B = Operand2 operator operator2
Some typical binary operations used in computing include
- Equal (==)
- Not equal (!=)
- Less than (<)
- Greater than (>)
- Greater than or equal to (>=)
- Less than or equal to (<=)
- Logical AND (&&)
- Logical OR (||)
- Addition (+)
- Subtraction (-)
- Multiplication (*)
- Division (/)
Let us discuss each one of them.
Equal (==)
In Java, the == operator is a particular class of relational operator that is used to examine equality relations. After the comparison, it gives a Boolean result, which is frequently used in looped statements and logical if-else expressions.
Let us understand it with an example program.
File name: Equal.java
// Programming in Java for the == operation
import java.io.*;
public class Equal {
public static void main(String[] args)
{
// declaring fundamental values
int k = 8;
int l = 8;
int m = 9;
// Using the == operator to compare two things
System.out.println("Are " + k + " and " + bl
+ " equal? " + (k == l));
// Using the == operator to compare k and m
System.out.println("Are " + l + " and " + m
+ " equal? " + (l == m));
}
}
Output
Are 8 and 8 equal? true
Are 8 and 9 equal? false
Not Equal (!=)
Java's Not Equal Relational Operators would be used to determine whether the left operand and the second operand are not equal.
The Not Equal operation is represented by the symbols !=.
As seen in the following, the Not Equal operator requires two operands: the left operand and the right operand.
A != B
Let us understand it with an example program
File name: Notequal.java
public class Notequal {
public static void main(String[] args) {
int f = 10;
int c = 17;
if (f != c) {
System.out.println("f and c are not equal.");
} else {
System.out.println("f and c are equal.");
}
}
}
Output
f and c are not equal
Less Than (<)
The very first operand is compared to the second operand to see if it is less or not. When the operand on the left is less than the operand on the right, the operator returns true. In contrast to the greater-than operator, it operates differently.
Let us understand it with an example.
File name: Lessthan.java
// Code in Java to Demonstrate the Less Than Operator
import java.io.*;
class Lessthan {
public static void main(String[] args)
{
Int d = 45, e = 12
// Two variables are compared, and the resulting boolean value is reported.
System.out.println("d < e: " + (d < e))
}
}
Output
d < e: False
Greater Than (>)
This checks whether the first operand is greater than the second operand or not. The operator returns true when the operand at the left-hand side is greater than the right-hand side.
Let us understand it with an example.
File name: Greaterthan.java
// Code in Java to Demonstrate the Greater Than Operator
import java.io.*;
class Greaterthan {
public static void main(String[] args)
{
int r= 22, d= 20;
// displaying the corresponding boolean value and comparing variables r and d
System.out.println("r > d: " + (r > d));
}
}
Output
r > d: true
Greater Than or Equal to (<=)
This determines if the first operand exceeds or is identical to the second operand. When the operand on the left is equal or greater to the operand on the right, the operator returns true.
Let us understand it with an example.
File name: Greatequal.java
// Greater than or equals to Operator in Java Program
import java.io.*;
class Greatequal {
public static void main(String[] args)
{
int r=19, m=13;
// showing the corresponding boolean value and comparing variables var1 and var2
System.out.println("r >= m: "+ (r >= m));
}
}
Output
r>=m: true
Less than or Equal to(<=)
The first operand must be smaller than or equal to a second operand for this to be true. When the operand on the left is less than and equal to the operand on the right, the operator returns true.
Let us understand it with an example.
File name: Lessequal.java
// Java Example of Less Than or Equal To Operation
import java.io.*;
class GFG {
public static void main(String[] args)
{
int k = 10, p = 11;
// displaying the corresponding boolean value and comparing p and k
System.out.println("p <= k: "
+ (p <= k));
}
}
Output
p <= k: false
Logical AND
When both of the requirements being considered are met or are true, this operator returns true. The operator produces a false result if any one of those two yields false. Cond1 && cond2 yields true if both condition 1 and condition 2 are true, to put it simply (i.e. non-zero).
Let us understand it with an example.
File name: LogicalAND
// Example Java code for the logical AND operator
import java.io.*;
class LogicalAND {
public static void main(String[] args)
{
// defining variables
int a = 10, b = 20, c = 20, d = 0;
System.out.println("V1 = " + a);
System.out.println("V2 = " + b);
System.out.println("V3 = " + c);
// using the AND logic to confirm two criteria
if ((a < b) && (b == c)) {
d = a + b + c;
System.out.println("The sum is: " + d);
}
else
System.out.println("False conditions");
}
}
Output
V1 = 10
V2 = 20
V3 = 20
The sum is: 50
Logical OR
When one of the two requirements being considered is met or is true, this operator returns true. The operator produces a true result indeed if a single of the two provides true. Both constraints must return false for the result to be false.
Let us understand it with an example.
File name: LogicalOR.java
// An example of the logical OR operator in Java
import java.io.*;
class Logical {
public static void main(String[] args)
{
// defining variables
int a = 10, b = 1, c = 10, d = 30;
System.out.println("V1 = " + a);
System.out.println("V2 = " + b);
System.out.println("V3 = " + c);
System.out.println("V4 = " + d);
// comparing two restrictions with logical OR
if (a > b || c == d)
System.out.println("One or both + the conditions are true");
else
System.out.println("Both the + conditions are false");
}
}
Output
V1 = 10
V2 = 1
V3 = 10
V4 = 30
One or both the conditions are true
Addition (+)
This binary operator is employed to combine two operands.
Let us understand it with the help of a program.
File name: Addition
// Example Java code for the addition operator
import java.io.*;
class Addition {
public static void main(String[] args)
{
// defining variables
int v1 = 10, v2 = 20, sum ;
// Displaying them
System.out.println("v1 = " + v1);
System.out.println("v2 = " + v2);
sum = num1 + num2;
System.out.println("The sum = " + sum);
}
}
Output
v1 = 10
v2 = 20
The sum = 30
Subtraction
Two operands can be subtracted using this binary operator.
Let us understand it with an example.
File name: Subtraction.java
// An example of the Subtraction operator in Java
import java.io.*;
class Subtraction {
public static void main(String[] args)
{
// defining variables
int v1 = 20, v2 = 10, sub;
System.out.println("v1 = " + v1);
System.out.println("v2 = " + v2);
sub = v1 - v2;
System.out.println("Subtraction = " + sub);
}
}
Output
v1 = 20
v2 = 10
Subtraction = 10
Multiplication
Two operands can be multiplied using this binary operator.
Let us understand it with an example.
File name: Multiply.java
// Example Java code for the Multiplication operator
import java.io.*;
class Multiply {
public static void main(String[] args)
{
// defining variables
int v1 = 20, v2 = 10, mult = 0;
System.out.println("v1 = " + v1);
System.out.println("v2 = " + v2);
mult = v1 * v2;
System.out.println("Multiplication = " + mult);
}
}
Output
v1 = 20
v2 = 10
Multiplication = 200
Division (/)
Dividing the first operand (dividend) by the subsequent operand (divisor) using this binary operator to get the quotient as the outcome.
Let us understand it with an example.
File name: Divide.java
// An example of division operator in Java
import java.io.*;
class Divide {
public static void main(String[] args)
{
// defining variables
int v1 = 20, v2 = 10, div = 0;
System.out.println("v1 = " + v1);
System.out.println("v2 = " + v2);
div = v1 / v2;
System.out.println("Division = " + div);
}
}
Output
v1 = 20
v2 = 10
Division = 2
