  public class HelloWorld{

      public static void main(String[] args) {

  int age1=24;

  int age2=18;

  int age3=36;

  int age4=27;

  int sum=age1+age2+age3+age4;

  int avg=(age1+age2+age3+age4)/4;

  int minus=(age1-age2);

  int newAge=age1--;

  System.out.println("年龄总和："+sum);

  System.out.println("平均年龄："+avg);

  System.out.println("年龄差值："+minus);

  System.out.println("自减后的年龄："+newAge);

  
  

  }

  }

  int newAge = age1--; 结果是 newAge = 24; age1 = 23;
