NullPointerException occurs, when you try to implement an application without referencing the object and allocating to a memory.

Example

public class javaerrornullpointerexception {

  public static void main(String args[]) {
  String string[] = new String[5];  
  System.out.println(string[1].charAt(1));

  }
}
