is that a rule for java?

what do you mean by missing? I put my return statement into an else statement

when i put
return true after the for loop
my program works
for (int i = 2; i <= n / 2; i++)
{
if (n % i == 0)
{
return false;
}

public class Programme {

there is no error for this code:

public static void main(String[] args) {

int count = 0;

for (int i = 10; i < 50; i++) {
if (isprime(i)) {

I have a question and I almost completed this. However, have a simple problem which I can't solve.

Design and implement a program that uses for loops to print the following rectangular pattern...

I have a better idea

import java.util.Scanner;

public class FirstProgramme
{
public static void main(String[] args)
{

System.out.print("Please enter a number: ");

Hello,
thanks for your comment
this is my new code
int a;
a=1;
System.out.println("Please enter a number: ");
Scanner in=new Scanner(System.in);
int n=in.nextInt();
while ( a<n)
...

first read a positive integer value, n, from the user
Write a while loop to output the integer values from 0 up to n exclusive. The output should have five values per line, with values separated...

I think I've solved the question by doing that

import java.util.Scanner;

{
