Local Variables are defined inside methods, constructors or blocks. These variables are declared and initialized within the method and are destroyed when the method completes.

Local Variables

Here is the video tutorial of Field and Methods in Java:

Local variables are declared within the body of a function, its life is the time when method is being executed. Once method completes it execution the local variable is also removed and destroyed by JVM. Local variables are very useful if you have to perform some work in the method and don't want the temporary data.
