Two Sample Questions for the Java Placement Exam

  1. Fill in the spaces marked with ______ to complete the following Boolean expressions. Do not use the Boolean operator "!" in your answer. Write only in the spaces marked with ______. Assume that X, Y and Z are integer variables.

    • An expression that is true if X is strictly the largest of the three variables X, Y and Z. For example, if X is 50, Y is 40 and Z is 45, the expression should be true, but if X is 50, Y is 40, and Z is 50, the expression should be false, since X is not strictly greater than Z.
