1.Assuming that x, y, and z are double variables, write a Java statement that implements this mathematical operation: set z to square root of y

2. Assuming stringVal is a String variable that contains a string representation of an int number, and intVal is an int variable, write a Java statement that converts what's in stringVal to an int and then assigns it to intVal.

3. Complete the code for the following for loop:

 for (int i = 1; i <= 6; i++) { //your code here } 

so that it prints the following numbers, one per line:

 -4 14 32 50 68 86
