java - Sum elements of an array, what am I doing wrong? -


so i'm trying see if elements of array divisible sum, think wrong for-loop sums elements of array, tips on how should proceed?

 public static void main(string[] args) {      int apa[] = {3,3,3};      system.out.print(allequal(apa));   }  public static boolean allequal(int[] a) {     int summa = 0;     boolean svar = true;     (int = 0; <= a.length; i++) {         summa +=a[i];      }     if (summa % a.length == 0) {         return svar;     } else {         svar = false;         return svar;     }  } 

public static void main(string[] args) {      int apa[] = {3,3,3};      system.out.print(allequal(apa));   }  public static boolean allequal(int[] a) {     int summa = 0;     boolean svar = true;     (int = 0; < a.length; i++) { // <-- here // if == a.length, arrayindexoutofboundsexception raised         summa +=a[i];      }     if (summa % a.length == 0) {         return svar;     } else {         svar = false;         return svar;     }  }
