• 方法定义的格式


     1 package day05;
     2 
     3 public class MethodDemo01 {
     4     /*方法定义的格式:
     5      *   public static void 方法名(){
     6      *   方法体
     7      * }
     8      * 方法的调用格式:
     9      *   方法名();
    10      * 注意:方法与方法之间是平级关系,不能嵌套定义*/
    11     public static void main(String[] args) {
    12         eat();
    13     }
    14 
    15 
    16     public static void eat() {
    17         study();
    18         System.out.println("eating");
    19     }
    20 
    21     public static void study() {
    22         System.out.println("learning");
    23     }
    24 }

    执行结果:

     eg:

     1 package day05;
     2 
     3 public class MethodDemo02 {
     4     public static void main(String[] args) {
     5         method();
     6     }
     7 
     8     public static void method() {
     9         int num = 16;
    10         if (num % 2 == 0) {
    11             System.out.println("偶数");
    12         } else {
    13             System.out.println("奇数");
    14         }
    15     }
    16 }
