Java Greater Number Using Loop

by

In this tutorial, we will learn about loops in Java and we will see the example with output.

Find Greater Numbers Using Loop in java

Each time my output prints the last number given through the scanner as the largest number. The program needs to be modified in a way that it scans through the number I input and prints the largest number.

Find the largest number using the while loop in java

In this program, we will learn to find the largest number using a while loop. In this, you have to understand the while loop and if statement then you can easily solve it.

Example-1

import java.util.Scanner;

public class LargestNumber {

public static void main (String [] args) {

int counter = 1;
int number;
int largest = 0;

Scanner inputs = new Scanner (System.in);
System.out.println ("Enter a Number:");
number = inputs.nextInt();

while (counter < 10)
    {
        
    System.out.println ("Enter the Number:");
    number = inputs.nextInt();

if (largest < number){
largest = number;
}

counter ++;
}
System.out.println ("largest number" + largest);
}
}

Output:

Example 2: Print a greater number using Loop in Java

import java.io. *;
import java.util. *;
public


class LargestNumLoop {
public static void main(String[]args)
{
int small = Integer.MAX_VALUE;
int number;
int large = 0;
int secondlarge = 0;

Scanner inputs = new Scanner (System.in );
System.out.println ("Enter a Number:");
number = inputs.nextInt();

large = number;
small = number;
secondlarge = number;

for (int x = 9; x > 0; x--)
{

System.out.println ("Enter" +x+ " more Number:");
number = inputs.nextInt();

if (number >= large){
secondlarge = large;
large = number;
}
else if (number > secondlarge){
secondlarge = number;
}
if (secondlarge < small){
small = number;
}

}
System.out.println ("largest number is: " + large+ "and the smallest number is:"+small);
}
}

Output:
