以下示例显示java.io.PrintWriter.print()方法的用法。
package com.jc2182;
import java.io.*;
import java.util.Date;
public class PrintWriterDemo {
public static void main(String[] args) {
Object obj1 = "Object";
Object obj2 = 2;
Date date = new Date(112, 2, 21);
try {
// create a new writer
PrintWriter pw = new PrintWriter(System.out);
// print object
pw.print(obj1);
// change the line
pw.println();
// print another object
pw.print(obj2);
// change the line
pw.println();
// print a date (it is an object)
pw.print(date);
// flush the writer
pw.flush();
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
Object
2
