Making a file writable

Hi,I see class java.io.File has a public method setReadOnly(): boolean. But I don't see a reverse method, i.e something like setWritable().Is there a way to make a file writable, without resorting to JNI?I am using JDK 5.0Thank you

Install Java 1.6: there are numerous enhancements in the File class concerning permissions:

That's nice...But I'm bound to JDK 5.0. Can't use 6.0 in this project.Maybe File class is the wrong place to look for such a thing in 5.0.Doesn't at least NIO provide such a utility?Thanks.

Hi,By using JDK 5.0, we can not give write access to a file. It is possible in JDK 6.0. In case if you want to do it with JDK 5.0 itself, use the DOS command with Runtime, your problem will solve.What will you say ?
