Java基础方法重载的应用

public class OverloadTest04{
  public static void main(String[] args){
    U.p(10);
    U.p("abc");
    U.p(true);
    U.p(1.0);
  }
}
/* class U{//用方法重载封装了输出语句
  public static void p(byte b){
    System.out.println(b);
  }
  public static void p(short b){
    System.out.println(b);
  }
  public static void p(int b){
    System.out.println(b);
  }
  public static void p(long b){
    System.out.println(b);
  }
  public static void p(float b){
    System.out.println(b);
  }
  public static void p(double b){
    System.out.println(b);
  }
  public static void p(boolean b){
    System.out.println(b);
  }
  public static void p(char b){
    System.out.println(b);
  }
  public static void p(String b){
    System.out.println(b);
  }
} */
