My computer does not have the How to make a file and with what software?

Ok, so I made it with my text editor and wrote this:
expecting Nimbus. I still get Metal. Why?

another way to specify the current L&F is to use the file to set the swing.defaultlaf property. This file, which you may need to create, is located in the lib directory of Sun's Java release (other vendors of Java may use a different location). For example, if you're using the Java interpreter in javaHomeDirectory\bin, then the file (if it exists) is in javaHomeDirectory\lib
