1. Will the following code compile, and if not, which line or lines will cause a compile error?

Line 1: public void myMethod() { Line 2: int sum = 0; Line 3: while (i<3) { Line 4: sum += i; Line 5: System.out.println("i = " + (i++)); Line 6: } Line 7: System.out.println(sum); Line 8: }

	1.	Line 4 and 7 have errors.
	2.	Line 6 has an error.
	3.	Lines 3, 4, and 5 have errors.
	4.	Line 1 has an error.
	5.	There are no compile errors - it will compile correctly.

2.

What will be the value of total after the following code is executed?

int total = 4; int myVariable1 = 12; int myVariable2 = 7; if (myVariable1 > myVariable2) { myVariable1 += myVariable2; total+= myVariable1; } else { myVariable2 += myVariable2; total+= myVariable2; }

3.

What will the value of myVar be after the following statements are executed?

int myVar = 0; myVar = 13 / 4; switch (myVar) { case 4: myVar += 5; break; case 3: myVar -= 5; break; default: myVar *= 3; }
