Parameter passing and parameter return for Java

The Java parameter passing is divided into: basic type passing and reference type passing.

Basic type delivery: True values are passed

Reference type passing: the address (array, object) of the referenced object is passed

Example:

1. Basic type:

public void setnumber (int num) {

｝

2. Reference type:

public void Setstudent (Student s) {

}

Second, Java parameter return: base type and reference type

Returns the base type: Returns the actual value to the caller

Returns the reference type: Returns the address of the object or array to the caller

1. Return the basic type:

public int GetNumber () {

}

2. Return the reference type:

Public Student Getstundt () {

}
