for loops not working

[nickbrickmaster]

Any code I put inside a for loop never happens.
Here is my code, just to test for loops:

Code: Select all

public class Test {
   public static void main(String[] args) {
      
      for (int i=0;i==7;) {
         LCD.drawString("Hello!", 0, i);
      }
      Button.waitForAnyPress();
   }

}


I am using the latest version of LeJOS with Eclipse and the plugin.
Any help would be appreciated.

Yes, you don't seem to understand how for loops work. Try the following:

Code: Select all

public class Test {
   public static void main(String[] args) {
     
      for (int i=0;i<7;i++) {
         LCD.drawString("Hello!", 0, i);
      }
      Button.waitForAnyPress();
   }

}

"for (A; B; C){D}" translates into "A; while(B){D; C}". The code you posted translates into

Code: Select all

int i=0;
while (i==7) {
         LCD.drawString("Hello!", 0, i);
}

I hope you see now, why it isn't working.

Oddly enough, for loops always worked that way for me. Thank you for pointing out I am an idiot.

I didn't say that.
