以下示例显示java.io.File.delete()方法的用法。
package com.jc2182;
import java.io.File;
public class FileDemo {
public static void main(String[] args) {
File f = null;
boolean bool = false;
try {
// create new file
f = new File("test.txt");
// tries to delete a non-existing file
bool = f.delete();
// prints
System.out.println("File deleted: "+bool);
// creates file in the system
f.createNewFile();
// createNewFile() is invoked
System.out.println("createNewFile() method is invoked");
// tries to delete the newly created file
bool = f.delete();
// print
System.out.println("File deleted: "+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-
File deleted: false
createNewFile() method is invoked
File deleted: true
