Methods with no parameters and return values in Java

First, define a tyrants class (Localtyrant)
Property: Name Moeney smoke
Behavior One: (No arguments no return value):
Behavior Two: (No parameters have return value):
Behavior Three: (with parameters have return value):
Behavior four: (with parameter no return value):
The following examples to look carefully, and slowly analysis, must not be anxious for haste

Package cm.tr;
    Class localtyrant{String name;
    int money;
    String Somke=null; * * Type one: no parameter no return value * Format: public void Method Name () {* Method body *} */public void fun1 () {SYSTEM.OUT.PR
    INTLN (name + "Running"); 
    /* * Type two: No parameters have return value * Format: Public return value type method name () {* Method body *return Value//return value must be the same as return value type *} *
        public string fun2 () {string str = "Express";      return str; There must be return value}/* * Type three: have parameters have return value * Format: Public return value type method name (parameter 1, parameter 2, ...) {* Parameters can have multiple, in the middle separated by a comma * method body *return return value *}/Public String fun3 (int money) {If [Money &G
        T;=25) {Somke = "Furong King";
        }else{Somke = "Huangshan";
    return Somke; /* * Type four: Parameter no return value * Format: Public return value type method name (parameter 1, parameter 2, ...)  {* Method Body *}/public void Fun4 (String apple,int money) {System.out.println (name + charity) + Apple
    + "and" +money + "block Money"); } public String TOstring () {return "self-introduction:" + name + "There are a lot of" + money+ "RMB"; Type must be String, method name must be ToString, cannot be modified} public class Demo2 {public static void main (string[] args) {//To
        Do auto-generated method stub localtyrant th= new Localtyrant ();
        th.money= 100;
        Th.name = "John";
        Method One: System.out.println ("self-introduction:" + th.name + "There are many" + th.money+ "RMB");  Method Two: The ToString method must cooperate with the public String toString () System.out.println (Th.tostring ()) in the definition class.
        You can also write//system.out.println (th); This method automatically invokes the call to the ToString Method//Method One: The method th.fun1 () is invoked without a parameter return value;
        Invocation of method Two: Calling a method that has no parameter return value must receive the return value in order to output the returned object String s = th.fun2 ();
        System.out.println (s);
        Equivalent to System.out.println (Th.fun2 ());
        Method Three invocation: The invocation has a return value System.out.println (TH.FUN3 (50));
        String Apple = "iphone 6plus";
        int money = 100;
         Method type Four invocation: There is no return value th.fun4 (Apple, money); Equivalent to Th.fun4 ("Iphone6plus", 100);Must give the parameter the same type of value}} 

Run Result:
Self Introduction: John has a lot of 100 yuan
Self Introduction: John has a lot of 100 yuan
John is running.
Express
Lotus King
John Dole out iphone 6plus and 100 bucks

PS: Clarify several methods in Java, easy to confuse
instance methods, class methods, and construction methods are distinguished in Java :
class method with the static modifier
Typical main function: public static void Main (String args[]) {}
Instance method: Is the General method
Construct method: No return value (none in the Void), the method name is the same as the class name
public class test{
public static void MyMethod ();//class method
public void myMethod2 (); Instance method
public teat ();//constructor method, no return value, same method name as class name
public string GetInfo ()//This is a method that has a return value without arguments, and a method that returns a string type
}
