你还在用System.out.println吗？经过静态引用包你可以使用我的print啦！

package com.hotmail.liuxuewei.util;
import java.io.*;

public class Print {
  // Print with a newline:
  public static void print(Object obj) {
    System.out.println(obj);
  }
  // Print a newline by itself:
  public static void print() {
    System.out.println();
  }
  // Print with no line break:
  public static void printnb(Object obj) {
    System.out.print(obj);
  }
  // The new Java SE5 printf() (from C):
  public static PrintStream
  printf(String format, Object... args) {
    return System.out.printf(format, args);
  }
}

import java.util.*;
import static com.hotmail.liuxuewei.util.Print.*;

public class HelloDate {
  public static void main(String[] args) {
    print("Hello, it's: ");
    print(new Date());
  }
}
