Hi Friend,

The structure of Java programme is:

[Package declarations]

[Import statements]

[Class declaration]

[Method declaration]

eg:
package form;

import java.lang;
class Add{

public void addNumbers(){
int a=10,b=5;
int c=a+b;
System.out.println(c);
}
public static void main(String[] args) {
Add a=new Add();
a.addNumbers();
}
}

Thanks
