This is a java program to find kth largest element form the given sequence of numbers. We find the kth largest by sorting the sequence first and then returning the element at position N-k, which qualifies as the kth largest element of the sequence.

Here is the source code of the Java Program to Find kth Largest Element in a Sequence. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

`//This is a java program to find kth largest element in randomly generated sequence`

import java.util.Random;

import java.util.Scanner;

public class Kth_Largest

`{`

static int N = 20;

static int []sequence = new int[N];

public static void sort()

`{`

System.out.println("The Sequence is: ");

for(int i=0; i<N; i++)

System.out.print(sequence[i] + " ");

System.out.println();

int i, j, temp;

for (i = 1; i< N; i++)

`{`

j = i;

temp = sequence[i];

while (j > 0 && temp < sequence[j-1])

`{`

sequence[j] = sequence[j-1];

j = j-1;

`}`

sequence[j] = temp;

`}`

`}`

public static void main(String args[])

`{`

Random random = new Random();

for(int i=0; i<N; i++)

sequence[i] = Math.abs(random.nextInt(100));

Scanner sc = new Scanner(System.in);

System.out.println("Enter the kth largest to find");

int k = sc.nextInt();

sort();

System.out.println(k+"th largest element is " + sequence[N-k-1]);

sc.close();

`}`

`}`

Output:

$ javac Kth_Largest.java $ java Kth_Largest Enter the kth largest to find 5 The Sequence is: 77 20 91 48 29 55 2 53 29 7 20 91 78 21 87 81 49 53 77 1 5th largest element is 77
