    Default The value of x

    double x = 7 / 2 + 1.5;
    I think the answer is 5

    If n has the value 3, what is the value of the expression:

    2 + n * 2 > 9

    Thanks in advance,

    In Java, the answer is 4.5 - 7 and 2 are considered int's unless specified otherwise, so 7/2 = 3

    The expression gives the

    boolean object false

    because multiplication preceeds addition..and so 8>9 which results in false

    Its because the number used is an integer dataType...and not the double type..so if you add, subtract, multiply and divide the integer, the result is also an integer and not double.... so in that case 7/2=3 not 3.5
