I am using Win Vista. I have downloaded Java 6 and installed it properly. But I cannot find the Javac file in bin folder of program file. And becuase of this I am receiving an error message while compiling a java program as 'Javac is not recognised as external or internal ........". In fact, when I write a java program in bin folder, even though it is saved there, but the file cannot be seen there. So, can anyone have a solution to that problem?
