Write a program to input 10 integers and print the second largest number. Assume that there is at least one second largest number in the given set of integers.

For Example,

INPUT: Enter 10 integers:

12 35 46 22 34 56 78 89 23 21

OUTPUT: Second Largest Integer: 78

Solution

import java.util.*;
class SecondLargest
{
	public static void main(String arr[])
	{
		Scanner sc=new Scanner(System.in);
		int l=0,sl=0,i,c=0,n;
		System.out.println("Enter 10 numbers:");
		for(i=1;i<=10;i++)
		{
			n=sc.nextInt();
			if(i==1)
				l=n;
			else if(n>l)
			{
				sl=l;
				l=n;
			}
			else
			{
				if(l!=0)
				{
					if(sl==0)
						sl=n;
					if(n>sl)
						sl=n;
				}
			}
		}
		System.out.println("Second Largest="+sl);
	}	
}
