1. (3% each) Given the following declarations: int a-4 int b-6: float5.0 Evaluate the following Java expressions: a) (5 + a / b) % 2- b) c / (10 % b) C) 5 * 300 7 + 8 / 3-6
Assume the following declarations: int b[] = {10, 20, 30}; int *x = b + 1; Choose all the expressions that are defined and evaluate to 10 A. *b B. b[1] C. *x D. x[-1] E. x[1] - b[1]
In JAVA, use this declaration and initialization: int theList[] = new int[4]; theList[0] = 1; theList[1] = -7; theList[2] = 10; theList[3] = 23; Write the method aNumLess(int list[], int x) which returns the number of data values in array theList which are less than value x.
QUESTION 1 Using the following declarations and a member of the Array class, int [ ] bArray = new int [10]; int location; Using a method in the Array class, write a statement that would change the order of the elements in the bArray array. The contents of the first cell should hold what was in the last cell. The second cell should hold what was in the next to last cell. __________________________ HINT: You must write the full statement...
After the following declarations and statements are executed: int i, j, k ; boolean c; float x, y, z; int[ ] num = {4, 1, 2, 3, 8}; i = 3; j = 5; x = 4.3; y = 58.209; c = !(i > j) ; what is the value of c
