UI - GRADE SIMPLE TASK

You have to first write in a .gradle file :-
apply plugin: 'java'
task(runSimple, dependsOn: 'classes', type: JavaExec) {
main = 'prime.java'
classpath = sourceSets.main.runtimeClasspath
}
defaultTasks 'runSimple'

Now in the folder prime.java you need to write the prime number code like that :-
class prime
{
public static void main (String[] args)
{

int i =0;
int num =0;
String prime = "";
for (i = 1; i <= 20; i++)
{
int counter=0;
for(num =i; num>=1; num--)
{
if(i%num==0)
{
counter = counter + 1;
}
}
if (counter ==2)
{
primeNumbers = prime + i + " ";
}
}
System.out.println(prime);
}
}
