intellij idea java文件只读不可编辑怎么解决？

你这边应该是文件吵烂不小心点告旁击到了锁定文件。打开锁定文件的窗口，选择File如图选项升友漏：

解锁则选择Make File Writeable

package com.yiibai

import java.io.File

import java.io.IOException

public class FileReadAttribute

{

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

{

File file = new File("c:/file.txt")

/逗卖/肆猛mark this file as read only, since jdk 1.2

file.setReadOnly()

if(file.canWrite()){

System.out.println("This file is writable")

}else{

System.out.println("This file is read only")

}

//revert the operation, mark this file as writable, since jdk 1.6

file.setWritable(true)

if(file.canWrite()){

System.out.println("This file is writable")

}else{

System.out.println("山雹逗This file is read only")

}

}

}
