Array Data Composite Web & Application int[] numbers = new int[3]; numbers[0] = 90; numbers[1] = 150; numbers[2] = 30; int a = numbers[0] + numbers[1]; // Sets variable a to 240 int b = numbers[1] + numbers[2]; // Sets variable b to 180 int[] numbers = { 90, 150, 30 }; int a = numbers[0] + numbers[1]; // Sets variable a to 240 int b = numbers[1] + numbers[2]; // Sets variable b to 180 int degrees = 360; float[] cos_vals = new float[degrees]; for(int i=0; i < degrees; i++) { cos_vals[i] = cos(TWO_PI/degrees * i); } An array is a list of data. It is possible to have an array of any type of data. Each piece of data in an array is identified by an index number representing its position in the array. The first element in the array is [0], the second element is [1], and so on. Arrays are similar to objects, so they must be created with the keyword new. Every array has a variable length which is an integer value for the total number of elements in the array. datatype[] var var[element] = value var.length datatype any primitive or compound datatype, including user defined classes var any valid variable name element int: must not exceed the length of the array - 1 value data to assign to the array element, must be the same datatype as the array 1.0 Object PDE
