Variables

Naming

• Named in lowerCamelCase convention.

Usage

• Declare variables close to the location where they are used.

Receiving variables

• If you get some getXY() method to store a reference to an Object, centralize the variable

/**/
public void someMethod( )
{
    final Object object = other.getObject();

    if ( checkCondition( ) )
    {
        object.someMethod( );
    }
    else {
        object.otherMethod( );
    }
}
/**/

Flags

• Declare once instanciated variables as final.

/**/
public void someMethod( )
{
    final String neverChanged = "foobar";
    // Other method content
}
/**/
