QN027. Write a program to print second greatest number of array elements.

---

1. Objective

To print second greatest number of array elements.

2. Theory

In this program we use nested loop and if statement. To find the largest element we arrange all the array elements in descending order and access index one element which is required output.

3. Source Code

public class Qn027{
public static void main(String[] args){
int arrayVar[] = {12, 6, 17, 9};
for(int i = 0; i<4; i++)
{
for(int j = i+1; j<4; j++)
{
if(arrayVar[i] < arrayVar[j])
{
int temp = arrayVar[i];
arrayVar[i] = arrayVar[j];
arrayVar[j] = temp;
}
}
}
System.out.println("Second greatest number is: " + arrayVar[1]);
}
}


4. Output

Second greatest number is: 12

5. Conclusion

In this way, I would like to conclude that, we can find the second largest element of array using descending order or ascending order and accessing array index.
