Hi,
        Here is a piece of code, i am trying to execute in
        JDK1.2pre-release. But it does not seem to be running.
        The code :
*******************************************************************
class test {
    public static void main(String Str[]) {
        int sum=0;
        int a=7;
        int b=7;

        for (int i=0;i<10;i++)  
            sum=(a*a*a*b) + (a*a*a*b)+ (a*a*a*b)+ (a*a*a*b);
    }
}
*******************************************************************
        ERROR:
java: ../../../../src/share/java/bcopt/Loop.C:374: boolean
