How to Creating Arrays in java?

Declaring arrays merely says what type of values the array will hold. It does not form them. Java arrays are objects, and such as any other object you use the new keyword to create them. While you create an array, you must tell the compiler how several elements will be stored in it. Here's how you'd form the variables declared on the previous page:

k = new int[3];
yt = new float[7];
names = new String[50];

The numbers within the brackets specify the length of the array; in which is, how many slots it has to hold values. With the lengths above k can hold three ints, yt can hold seven floats and names can carry fifty Strings. This step is sometimes known as allocating the array since it sets aside the memory the array needs.
