A method with parameters

I. Methods with parameters:

Syntax: The access modifier method returns a value type method name (parameter list) {

Method body

}

For example: public void Searchname (String name,int start,int end) {

Method body

}

Note: Separate each parameter with ",".

Two. Formal parameters and arguments

Formal parameter: The argument specified when the method is defined.

Arguments: Parameters that are specified when the method is called.

Three. Issues to be aware of when invoking a parametric method: 1. The parameter data types of the formal parameters and arguments are consistent.

2. The order of formal parameters and arguments is consistent.

3. The number of formal parameters and arguments remains the same.

Four. Object array:

For example: Student [] students=new student[30]; An array of student objects with a size of 30 is declared.

//Student name class
Public classStudent {//Create an array of length 10String []names=NewString[10]; //Initialize     Public voidinit () {names[0]= "Zhang San"; names[1]= "John Doe"; names[2]= "Harry"; names[3]= "Zhao Liu"; names[4]= "Sun Seven"; names[5]= "Ma Yuan"; names[6]= "Ma Total"; names[7]= "Zhengnan"; names[8]= "Shadow sister"; names[9]= "Shadow Total"; }    //Find student Names     Public BooleanStudent (String name,intStartintend) {        Booleanflag=false; //Cycle Judgment         for(inti = start-1; I <end; i++) {            if(names[i].equals (name)) {flag=true;  Break; }        }        returnFlag; }}

//Test class
ImportJava.util.Scanner; Public classteststudent { Public Static voidMain (string[] args) {//Creating ObjectsStudent stu =NewStudent (); //Calling MethodsStu.init (); Scanner input=NewScanner (system.in); System.out.println ("Please enter the student's name:"); String name=Input.next (); //Judging        if(Stu.student (Name, 3, 6) {System.out.println ("I found it!" "); } Else{System.out.println ("Not Found!" "); }    }}
