Java Integer min() method

The min()  method of Integer class returns the smaller of two int values. It returns the same result as by calling Math.min.  Syntax public static int min(int a, int b) Parameters The parameters ‘a’ and ‘b’ represent the first and second operand.  Return Value This method returns the smaller of ‘a’ and ‘b’. Example 1

public class JavaIntegerMinExample1 {
    public static void main(String[] args) {
        Integer val1=134;
        Integer val2=567;
        // returns the smaller of two values
        int min=Integer.min(val1,val2);
        System.out.println("The smaller number between "+val1+" and "+val2+" is "+min);
    }
}

Output

The smaller number between 134 and 567 is 134

Example 2

import java.util.Scanner;
public class JavaIntegerMinExample2 {
    public static void main(String[] args) {
        Scanner scanner= new Scanner(System.in);
        System.out.print("Enter the total number : ");
        int n=scanner.nextInt();
        System.out.println("Enter "+n+" elements : ");
        int min=0;
        int[] a= new int[n];
                for (int i=0;i<n;i++ ){
            a[i]=scanner.nextInt();
        }
        for (int i=0;i<n;i++){
            for (int j=i+1;j<n;j++){
                min=Integer.min(a[i],a[j]);
                if (a[j]==min){
                    a[j]=a[i];
                    a[i] =min ;
                }
            }
        }
           System.out.println("The smallest number is "+a[0]+" ");
    }
}

Output

Enter the total number : 5
Enter 5 elements :
198
66
0
98
78
The smallest number is 0

Example 3

import java.util.Scanner;
public class JavaIntegerMinExample3 {
    public static void main(String[] args) {
        Scanner scanner= new Scanner(System.in);
        System.out.print("Enter the total number : ");
        int n=scanner.nextInt();
        System.out.println("Enter "+n+" elements : ");
        int[] a= new int[n];
                for (int i=0;i<n;i++ ){
            a[i]=scanner.nextInt();
        }
        for (int i=0;i<n;i++){
            for (int j=i+1;j<n;j++){
                int min=Integer.min(a[i],a[j]);
                if (a[j]==min){
                    a[j]=a[i];
                    a[i] =min ;
                }
            }
        }
        System.out.print("Ascending Order : ");
        for (int i=0;i<n;i++) {
           System.out.print(a[i]+" ");
        }
    }
}

Output

Enter the total number : 5
Enter 5 elements :
12
456
98
7
34
Ascending Order : 7 12 34 98 456
