    Default The problem with Java and CPU usage, need HELP

    Thank You for your reply!
    I write it in Java Language, yes i launch then all in the same time, every program will not require very much processor time, because if i run it in one language it is almost OK, working very normally, I am using DELL laptop i5 2.67GHz processor with 4GB RAM, and Java 1.7 JDK. each program just doing as an Automatic Transfer Money machine is do, namely (Deposit, Withdraw, Transfer money, Balance in Query, Exit) i think it is not much complex, there is three classes for each language, and three classes which every language shared like Database class which has the get Connection and so on method which is used by these three languages. and at the end one other class is used to collect these three languages to one, the class name is AllInOneFrame, the other classes is extended JPanel, and implements Key, Action, and Mouse Listeners, and the AllInOneFrame class is extended the JFrame, when i run this class the CPU usage dramatically goes to 100, and Computer become very slow.... I don't if there is any way to post the Project, because if i post the entire code it is very long, but i will post the last AllInOneFrame class for more information. thank you
