以下示例显示java.io.File.getAbsoluteFile()方法的用法。
package com.jc2182;
import java.io.File;
public class FileDemo {
public static void main(String[] args) {
File f = null;
File f1 = null;
String path = "";
boolean bool = false;
try {
// create new files
f = new File("test.txt");
// create new file in the system
f.createNewFile();
// create new file object from the absolute path
f1 = f.getAbsoluteFile();
// returns true if the file exists
bool = f1.exists();
// returns absolute pathname
path = f1.getAbsolutePath();
// if file exists
if(bool) {
// prints
System.out.print(path+" Exists? "+ bool);
}
} catch(Exception e) {
// if any error occurs
e.printStackTrace();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
D:\EclipseAndroid\IO\BufferedInputStream\test.txt Exists? true
