How we Declaring Arrays in java language?

Like all other variables in Java, an array must have a exact type such as byte, int, String or double. Just variables of the appropriate type can be stored in an array. One array cannot store both ints and Strings, for instance.

Such as all other variables in Java an array must be declared. While you declare an array variable you suffix the type along with [] to denotes in which this variable is an array. Here are some examples:

int[] k;
float[] yt;
String[] names;

This says that k is an array of ints, yt is an array of floats and names is an array of Strings. Instead you declare an array such as you declare any other variable except in which you append brackets to the end of the type.

You also have the option to append the brackets to the variable instead of the type.
int k[];
float yt[];
String names[];

Therefore, unlike in C, you cannot include the length of the array in the declaration. The subsequent is a syntax error:
int k[3];
float yt[7];
String names[100];
int k[];
float yt[];
String names[];
