boolean expressions

1. Evaluate the following boolean expressions. For each of the following expressions, assume x is 10, y is 20, and z is 30. Indicate which of the following boolean expressions are always true and which are always false, regardless of the values for x, y, or z.

a. x < 10 || x > 10 b. x > y && y > x

c. (x < y + z) && (x + 10 <= 20) d. z - y == x && Math.abs(y - z) == x

e. x < 10 && x > 10

f. x > y || y > x

g. !(x < y + z) || !(x + 10 <= 20) h. !(x == y)) && (x != y) && (x < y || y < x)

 

2. Express the following switch statement by using nested if statements.

switch (grade){

case 10:

 

case

9:

a = 1;

 

 

b = 2;
