I'm trying to generate number's bigger than 3, i made an if statement, but this code is keep generating smaller numbers.

Question

public class Program
{
public static void main(String[] args) {
int myArray [] = new int [4];
int f = 20;
while (f > 1) {
for (int i = 0; i < myArray.length;i++){
if (f > 3 && f < 21) {
myArray [i] = (int) (1+Math.random()*f);
System.out.println(myArray[i]);
f = f - 4;
} else if (f < 3 || f > 20) {
continue;
}
}
}

}
}

Answer 1

Some unnecessary parts of your code are:
-> f<21 (no need to check for that condition since f will always be less than 21)
->the else block is useless since there is no code to run after it and it doesn't contain any useful code.

Your code is generating numbers greater than 3 when I ran it. Can't figure out what you mean.

Answer 2

Yeah i saw f < 21 is not necessarily after i write the code, but i could bother to delete it, the reason i made an else statement is because if number is less then 3 i don't want f to get deducted by 4.

Answer 3

I fix it bthw, thank you for responding!!

public class Program
{
public static void main(String[] args) {
int myArray [] = new int [4];
int f = 20;
while (f > 1) {
for (int i = 0; i < myArray.length;i++){ myArray [i] = (int) (1+Math.random()*f);

if (myArray [i] > 3) {

System.out.println(myArray[i]);
f = f - 4;
}
}
}

}
}
