Hi, i have windows 7 system and now i got problem during run java program on my system command prompt. i already installed java developer kit from Sun Microsystems, and JRE on my system. it installed successfully without any problem. today, i just made one java program and then try to run it on the command prompt using the javac command. My java file name is Javatest. So, i try to execute javac Javatest.java on command prompt as per mentioned in book. Then command prompt show me error "command not found". How is that possible?? i correctly installed java compiler on it but it won't detect in command prompt. Need help to fix this problem.
