Here is the code to find nth prime number.

import java.util.Scanner;
public class NthPrime {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.print("Enter n to compute the nth prime number: ");
int nth = sc.nextInt();
int num, count, i;
num=1;
count=0;
while (count < nth){
num=num+1;
for (i = 2; i <= num; i++){ //Here we will loop from 2 to num
if (num % i == 0) {
break;
}
}
if ( i == num){//if it is a prime number
count = count+1;
}
}
System.out.println("Value of nth prime: " + num);
}
}

Output:

Enter n to compute the nth prime number: 5
Value of nth prime: 11
