class How to write a class.
setumeiclass.java
public class setumeiclass/*⇐ File name*/{
//Write the main method in this.
}
It won't start without this. Write the code in this. (Basically.)
Test.java
public class Test{
public static void main(String args[]){
/*Write the code here!!*/
}
}
rei.java
public class rei{
public static void main(String args[]){
System.out.println("Hello,World!!");
}
}
Hello,World!!
zisaku
public class zisaku{
public static typename method(argument){
Code executed by this method
}
public static void main(String args[]){
Use your own method here
}
}
myclass.java
public class myclass{
public static void main(String args[]){
myclass(1,2);
}
public static void myclass(int a,int b){
System.out.println(a+b);
}
}
3
Since the values of the arguments ʻa and
bof
myclass are 1 and 2, ʻa
+ b
(1 + 2) is 3.
