the close statement can be commented out, still things can be print to the file, but for the writer's example---ReaderWriter.java, you must use close , otherwise nothing can be printed out to the file, because reader's close is not the same as stream's close.*/ char c='z'; ps....

This is most serious on Windows because you cannot remove a file if there is an open handle to it. Example: PrintStream ps = null; File file = new File(fileName); /* PrintStream(File file, String csn) */ try { ps = new PrintStream(file, UNSUPPORTED_CHARSET); ...
For example: public class HelloInterrupted { public static void main(String[] args) { Thread.currentThread().interrupt(); if(Thread.currentThread().interrupted()) { // handle the interruption status here } System.out.println("Hello"); } } 26-09-2005 EVALUATION I've rolled this bug back...
在Java中,PrintStream类提供了一组方便的打印方法。print(String)方法是其中之一,它用于将字符串打印到输出流中。 语法 public void print(String str) 参数 str:要打印的字符串。 返回值 无。 实例 下面是使用PrintStream的print(String)方法的示例: import java.io.PrintStream; public class PrintStreamExample { ...
publicclassPrintStreamExample{publicstaticvoidmain(String[]args){intnum=10;Stringname="Java";System.out.println("Number is: "+num);System.out.println("Name is: "+name);}} 在上面的示例中,我们通过System.out.println()方法打印了两个变量的值。输出内容如下: ...
importjava.io.*;publicclassExample{publicstaticvoidmain(String[]args){floatf=3.14f;PrintStreamps=System.out;ps.print(f);}} 输出结果为: 3.14 此示例中,我们首先定义了一个float类型的变量f并将其赋值为3.14。然后,我们使用System.out对象创建了一个PrintStream对象ps,并调用了其print(float)方法将f打印到...
