Document Summary

Chapter 7 - arrays and the arraylist class. Introduction to arrays: array- an object that can hold a group of values of the same data type int[ ] numbers; float[] temperatures = new float [100]; char [] letters = new char [5]; [6] is the array"s size declarator (# of values it can hold) Each element is assigned a subscript (an index used to pinpoint the element in the array). The first number in the array ha the index of 0. Size = temperatures. length; the . length is how long the temperatures array is. For loops can still be used in arrays for (int index = 0; index < numbers. length; index++) showvalue(numbers[index]);
