Thread: whats wrong?

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)) {
count++;
System.out.println(i + "is a prime number. ");

if (count == 3) {
break;
}
}
}

}

public static boolean isprime(int n) {

if (n == 1) {
return false;
}

for (int i = 2; i <= n / 2; i++)
{
if (n % i == 0)
{
return false;
}

}
return true;

}
}

however when i put the "return true;" into an else statement like this i get an error. Why is that?
public class Programme {

public static void main(String[] args) {

int count = 0;

for (int i = 10; i < 50; i++) {
if (isprime(i)) {
count++;
System.out.println(i + "is a prime number. ");

if (count == 3) {
break;
}
}
}

}

public static boolean isprime(int n) {

if (n == 1) {
return false;
}

for (int i = 2; i <= n / 2; i++)
{
if (n % i == 0)
{
return false;
}
else
{
return true;
}
}


}
}

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;
}

}
return true;

}
}


but when i put return true into an else statement my program doesn't work like this

for (int i = 2; i <= n / 2; i++)
{
if (n % i == 0)
{
return false;
}
else
{
return true;
}
}

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

is that a rule for java?
