Actually, NO.
You need a decompiler to convert class files to java source files. JAD is a Java Decompiler that can do it for you.
install java, then it will work NOTE: The Game Maker Decompiler is ILLEGAL. You can only use it to decompile your own games if you lost the GMK, but still have the EXE.
You can't. You have to extract them directly from the Movies. Use a Flash Decompiler.
You'll need a brain first. Sadly, they're hard to source.
do you mean SWF convert to flash? if yes, you can try about SWF decompiler.
Hahahaha lets ask people to pirate things for us.
You really can't unless you get a decompiler. A .com file is a computer program that has been 'compiled' and converted into machine language. What you want is the 'source code' that was used to create the .com file by running it through a compiler.
This one is failry easy: http://www.messy-mind.net/2008/complete-gm-decompiler/
Knowing Java does not allow you to hack a Java program because the source code is not available to hackers. Also, a program interprets the bit-code before you see it, so even with a decompiler, hacking the program will not be possible.
Public instance variables are not dangerous, but can put your program at risk of being hacked. For instance, say the variable bacon is an integer that represents your health in a game, and its value is 50. Someone could change its value to 1,000,000 by using a program called a decompiler, then change the code, and recompile it.
right click on the class file ,go to properties and change open with to notepad, and then it can be opened.. :) While that may work, it is almost impossible to read as it is. What I suggest is downloading a java decompiler, then open it with that. It will convert it to what you would see in a .java file, which you are able to read if you know java programming.
