目标:写一个Java类,读取自己,并按照原来的格式输出到控制台。
源代码:
TestFile.java
package com.topsoft.icisrpt.domain._05_qd.entity;
import java.io.*;
/**
* Created by IntelliJ IDEA.
* File: TestFile.java
* User: leizhimin
* Date: 2008-1-28 16:56:21
*/
public class TestFile {
public static void main(String args[]) throws IOException {
File f = new File("D:\\TestFile.java");
LineNumberReader lineNumberReader = new LineNumberReader(
new FileReader(f));
StringBuffer sb = new StringBuffer();
String lineStr = lineNumberReader.readLine();
while (lineStr != null) {
sb.append(lineStr).append("\n");
lineStr = lineNumberReader.readLine();
}
System.out.println(sb.toString());
}
}
import java.io.*;
/**
* Created by IntelliJ IDEA.
* File: TestFile.java
* User: leizhimin
* Date: 2008-1-28 16:56:21
*/
public class TestFile {
public static void main(String args[]) throws IOException {
File f = new File("D:\\TestFile.java");
LineNumberReader lineNumberReader = new LineNumberReader(
new FileReader(f));
StringBuffer sb = new StringBuffer();
String lineStr = lineNumberReader.readLine();
while (lineStr != null) {
sb.append(lineStr).append("\n");
lineStr = lineNumberReader.readLine();
}
System.out.println(sb.toString());
}
}
控制台输出:
package com.topsoft.icisrpt.domain._05_qd.entity;
import java.io.*;
/**
* Created by IntelliJ IDEA.
* File: TestFile.java
* User: leizhimin
* Date: 2008-1-28 16:56:21

public class TestFile {
public static void main(String args[]) throws IOException {

LineNumberReader lineNumberReader = new LineNumberReader(
new FileReader(f));
StringBuffer sb = new StringBuffer();
String lineStr = lineNumberReader.readLine();
while (lineStr != null) {
sb.append(lineStr).append("\n");
lineStr = lineNumberReader.readLine();
}
System.out.println(sb.toString());
}
}
import java.io.*;

lineStr = lineNumberReader.readLine();
}
System.out.println(sb.toString());
}
}
呵呵,这是个测试例子,完成了。
