Question

Question 1

while loops can be used to implement counter-controlled repetition and while loops can be used to implement sentinel-controlled repetition. T/F

Question 2

Java does not require that local variables are initialized when declared, but does require that they are initialized prior to use in an expression. T/F

Question 3

Select only those options corresponding to Java's primitive types from the list below

		wide
		short
		float
		bit
		boolean
		byte
		String
		char
		double
		int
		long
		word

points

Question 4 . The following two statements are functionally equivalent (will achieve the same result): T/F

++var;

var++;

Answer 1

1. True, while loop is similar to for loop, counter can be implemented using while loop too.

2. False, local variable has default values, eg int has default value as 0

3.
short
float
boolean
char
int
long

4. False, ++var will first increase the value and then do the operation, vice versa with var++
