Inputs may range from the maximum to the minimum default range for the integer type. We should also include a zero test value. A suitable set of black box test cases is given in the table given to the right. Note that we replace the duplicate 0 with a 1 . This should also be done.
Some programming languages supports a number of predefined operations that can be applied to arrays.
For example equality checking or concatenation. Java does not provide such operators. Typically such variables describe features such as the lower bound, upper bound and length of an array. In Java the only array variable available is length . To use this we must use the dot operator to link it to appropriate array.
