Java Integer toString() method

The toString() method of Java Integer class returns a String object which represents this Integer’s value.

The second syntax returns a String object which represents the specified integer.

The third syntax returns a string representation of the specified argument in the radix specified by the given radix.

Syntax

public String toString ()
public static String toString (int i)
public static String toString (int i, int radix)

Parameters

The parameter ‘i’ represents an integer to be converted to a string and the parameter ‘radix’ represents the radix to use in the string representation.

Return Value

This method returns a String which represents the same value as this argument in base 10 or in the specified radix.

Example 1


public class JavaIntegerToStringExample1 {
    public static void main(String[] args) {
        Integer val=5667;
        String val1=Integer.toString(val);
        //It returns a string representation of the value of this object in base 10.
        System.out.println("String  Value : "+val1);
    }
}

public class JavaIntegerToStringExample1 {

public static void main(String[] args) {

Integer val=5667;

String val1=Integer.toString(val);

//It returns a string representation of the value of this object in base 10.

System.out.println("String Value : "+val1);

}

Output


String  Value : 5667

String Value : 5667

Example 2


public class JavaIntegerToStringExample2 {
    public static void main(String[] args) {
        Integer val=Integer.MAX_VALUE;
        String val1=val.toString();
        //It returns a string representation of the value of this object in base 10.
        System.out.println("String  Value : "+val1);
    }
}

public class JavaIntegerToStringExample2 {

public static void main(String[] args) {

Integer val=Integer.MAX_VALUE;

String val1=val.toString();

//It returns a string representation of the value of this object in base 10.

System.out.println("String Value : "+val1);

}

Output


String  Value : 2147483647

String Value : 2147483647

Example 3


public class JavaIntegerToStringExample3 {
    public static void main(String[] args) {
        Integer val=566787643;
        int radix=78;
        String val1=Integer.toString(val,radix);
        //It returns a string representation of the value of this object in the     specified radix.
        System.out.println("String  Value : "+val1);
    }
}

public class JavaIntegerToStringExample3 {

public static void main(String[] args) {

Integer val=566787643;

int radix=78;

String val1=Integer.toString(val,radix);

//It returns a string representation of the value of this object in the specified radix.

System.out.println("String Value : "+val1);

}

Output


String  Value : 566787643

String Value : 566787643

Example 4


public class JavaIntegerToStringExample4 {
    public static void main(String[] args) {
        //passing negative value
        Integer val=-5667;
        String val1=Integer.toString(val);
        System.out.println("Unsigned String  Value : "+val1);
        //calling string class methods
        StringBuffer sf= new StringBuffer(val1);
        StringBuffer reverse=sf.reverse();
        System.out.println("Reverse of "+sf+" : "+reverse);
    }
}

public class JavaIntegerToStringExample4 {

public static void main(String[] args) {

//passing negative value

Integer val=-5667;

String val1=Integer.toString(val);

System.out.println("Unsigned String Value : "+val1);

//calling string class methods

StringBuffer sf= new StringBuffer(val1);

StringBuffer reverse=sf.reverse();

System.out.println("Reverse of "+sf+" : "+reverse);

}

Output


Unsigned String  Value : -5667
Reverse of 7665- : 7665-

Unsigned String Value : -5667

Reverse of 7665- : 7665-
