How do I declare and initialize an array in Java?

There are two ways of declaring an array in java:

type variable-name[];

OR

type[] variable-name;

There are two ways of initializing an array in java:
1. Without assigning values

datatype [ ] arrayName = new datatype [size];

2. By assigning values

datatype [ ] arrayName={value1, value2, value3};

Type[] variableName = new Type[capacity];

Type[] variableName = {comma-delimited values};



Type variableName[] = new Type[capacity];

Type variableName[] = {comma-delimited values};
is also valid, but I prefer the brackets after the type, because it's easier to see that the variable's type is actually an array.
