Question

Find the odd one out with reason:

1. a++, a+=1, ++a, a+1
2. nextLine(), nextDouble(), nextFloat(), nextShort(), next()
3. Integer, Boolean, Float, Long
4. break, continue, goto, return
5. *, +, /, %
6. True, TRUE, "true", true

Answer 1

1. a+=1 because it increments the value of 'a' and assigns it to 'a' yet others increment the value of a only.
2. nextLine() because it reads an entire string together with spaces and display it
3. Boolean because it returns either true or false
4. return gives out the output as the others gives out the next instruction
5. % it returns the remainder of elements
6. "true" it is a string while others are Boolean values
