Ways of passing values to a function:
A method receives value passed from the caller program, carries out statements defined in it and returns the result to the caller program. You may invoke a method by passing different values as many times as you need. There are two ways of passing values to a function.
Pass by Value
In a 'Pass by Value' system, the values from the actual parameters are copied to the formal parameters. Hence, any change made in the formal parameter will not reflect any change in the actual parameter. By default, all primitive data types, viz. int, float, char, long, double, etc. are passed to a function by using 'Pass by value'.
Pass by Reference
In Java, primitive data parameters are passed by value (default), while object and array parameters are passed by reference (aliasing). This means formal and actual parameters share memory locations, so changes to formal parameters affect the actual parameters.
