Can someone explain what is wrong with my set methods?

[kenny gill]

 public boolean setProjectScore(double[] projects) {
		 
		 int a[0] = 96;
		 
		 return true;
	 }
	 
	 public boolean setQuizScore(double[] quizzes) {
		 
		 int b[0] = 88;
		 
		 return true;
	 }

here are the instructions:

These methods should return a boolean to indicate success or failure, depending on if the project or quiz number is out of the bounds of the array. The setProjectScore() and setQuizScore() methods will place the double value into the project or quiz number index of its respective array.
