Question

These are basic to Java9 expressions that just need to be evaluated to their simplest form. I got these ones wrong and just wanted to get some input as to why. Thank you for the assistance!

Evaluate the following expressions:

( ((10*5)+6/3)==(10*5)+(6/3) || true != 5>4)

4+3*80+"Hello" +4*9+45/2

!(!((3.5+1.0) >(9/2))&&(12%4==3) )

Answer 1

Answer:

1)
(((10*5)+6/3)==(10*5)+(6/3) || true != 5>4)
=>  ((50+6/3)==(10*5)+(6/3) || true != 5>4)
=>  ((50+2)==(10*5)+(6/3) || true != 5>4)
=>  (52==50+2 || true != 5>4)
=>  (52==52 || true != 5>4)
=>  true || true != true
=>  true || false
=>  true
Answer: true

2)
4+3*80+"Hello" +4*9+45/2
=>  4+240+"Hello" +36+22
=>  244+"Hello"+36+22
=>  "244Hello"+36+22
=>  "244Hello36"+22
=>  "244Hello3622"
Answer: 244Hello3622

3)
!(!((3.5+1.0) >(9/2))&&(12%4==3) )
=>  !(!(4.5 >4)&&(0==3))
=>  !(!(true)&&false)
=>  !(false&&false)
=>  !false
=>  true
Answer: true
