例题4-5常量的用法/例题4-6通过类名调用类

class Tom{
 final int MAX=100;
 static final int MIN=20;
}
public class Example4_5{
 public static void main(String args[]){
  System.out.println(Tom.MIN);
  Tom cat=new Tom();
  int x=0;
  x=Tom.MIN+cat.MAX;
  System.out.println(x);
 }
}

 

class Computer{
 double x,y;
 static double max(double a,double b){
  return a>b?a:b;
 }
}
class Example4_6{
 public static void main(String args[]){
  double max=Computer.max(12,45);
  System.out.println(max);
 }
}
