本文整理了Java中java.io.File.setReadOnly()方法的一些代码示例，展示了File.setReadOnly()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。File.setReadOnly()方法的具体详情如下：
包路径：java.io.File
类名称：File
方法名：setReadOnly

File.setReadOnly介绍

[英]Equivalent to setWritable(false, false).
[中]等同于可设置写（false，false）。

    File f2 = new File("blah2.txt");

    // All of these should generate a warning
    f.mkdir();
    f.mkdirs();
    f.delete();
    f.createNewFile();
    f.setLastModified(1L);
    f.setReadOnly();
    f.renameTo(f2);
  }
