java - How to delete elements from an array? -


how delete integer @ given index , how compress myints?

this got keep getting error.

public void deleteint(int index) {      int[] newints = arrays.copyof(myints, myints.length);      if (myints[index] != 0) {         myints[index] = 0;          (int : myints) {             if (myints[i] != 0) {                 newints[i] = myints[i];             }         }     }     myints = newints;     currentint++; } 

this error get:

exception in thread "main" java.lang.arrayindexoutofboundsexception: 11

this code doesn't use enhanced loop properly:

    (int : myints) {         if (myints[i] != 0) {             newints[i] = myints[i];         }     } 

it tries read element myints, content of element, not index. so, element contains value > array's length the outofbounds exception.

public void deleteint(int index) {      // can 1 element shorter going erase 1 element     // also, copying contents of original array in waste of time     // create it.     int[] newints = new int[myints.length-1];       // easiest way use variable track insertions in     // new array     int j=0;     (int i=0; < myints.length; i++) {         if (i != index) {             newints[j++] = myints[i];         }     }      // have new shortened copy of array, function void,     // life ends here :) }
