Java Integer max() method

The max() method of Integer class returns the greater of two int values. It returns the same result as by calling Math.max.

Syntax

public static int max(int a, int b)

Parameters

The parameters ‘a’ and ‘b’ represent the first and second operand.

Return Value

This method returns the greater of ‘a’ and ‘b’.

Example 1

public class JavaIntegerMaxExample1 {
    public static void main(String[] args) {
        Integer val1=134;
        Integer val2=567;
        // returns the greater of two values
        int max=Integer.max(val1,val2);
        System.out.println("The greater number between "+val1+" and "+val2+" is "+max);
    }
}

Output

The greater number between 134 and 567 is 567

Example 2

import java.util.Scanner;


public class JavaIntegerMaxExample2 {
    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 max=Integer.max(a[i],a[j]);
                if (a[j]==max){
                    a[j]=a[i];
                    a[i] =max ;
                }
            }
        }
        System.out.print("Descending Order : ");
        for (int i=0;i<n;i++) {
           System.out.print(a[i]+" ");
        }
    }
}

Output

Enter the total number5
Enter 5 elements :
12
56
90
34
76
Descending Order : 90 76 56 34 12

Example 3

import java.util.Scanner;
public class JavaIntegerMaxExample3 {
    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 max=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++){
                max=Integer.max(a[i],a[j]);
                if (a[j]==max){
                    a[j]=a[i];
                    a[i] =max ;
                }
            }
        }
           System.out.println("The greatest number is "+max+" ");
    }
}

Output

Enter the total number : 6
Enter 6 elements :
12
876
55
678
34
223
The greatest number is 876
