     public void setName(Name[] theName) {
          theName[0]=this.getNameInstance();
     private Name myNameInstance = new Name();
     public void setNameInstance(Name theNameInstance) {
          if(isValidName(theNameInstance)){

     public Name getNameInstance() {
          return myNameInstance;
     }I am getting an array Index out of bound eception in the method setName, Can any one tell me where I am doing wrong?

Answer 1

The array passed in must be empty. I suggest using the debugger for problems like these. If you don't know how to use the debugger, here's a start:
(Assuming you have a debugger, any IDE you'd be using will)
1. Set a breakpoint on or before your line of question. In this case, place it on the line of code in your setName() method. Set a breakpoint by either right clicking on that line and selecting "Add breakpoint," or simply click on the far left side of the editor window, right next to the line number. Either way, a little dot will appear to mark the breakpoint.
2. Execute your code in Debug mode rather than release mode. This might mean clicking on the little bug-looking icon "Debug" rather than "Run."
3. Your code will execute and you'll enter the debug perspective when that breakpoint is reached. There, in the variables window, you'll see your array and any information about it, particularly its size and contents.
