• expression

• statement

• operation

Answer explanation

Expression - the combination of operands and operators.

e.g.: a+b

Statement - Assignment of the expression to a variable.

e.g.: c = a+b

Operation -What happens when the statement is executed.

• a*r*r

• a*r

• a^r

• a*a*r

Which of these is NOT a type of operator in Java?

• Arithmetic

• String

• Relational

Arithmetic operators are: (mark all that apply)

• Unary

• Unitary

• Binary

• Ternary

• Tertiary

If:

c= -5

-c =?

• -5

• 5

• 0

If a=5:

The solution to:

(i) m= ++a*2 + a

and

(ii) m = a++*2 + a

are:

• (i) 18

  (ii) 16

• (i) 16

  (ii) 18

• (i) 17

  (ii) 16

• (i) 16

  (ii) 17

The correct list of binary arithmetic operators in Java

• +-*/

• +-*/^

• +-*/%

How many of these expressions are CORRECTLY matched with their shortform? Mark all that apply.

• a = a/5

  a / = 5

• a = a+5

  a++5

• a = a%3

  a% = 3

• a = a*5

  a = *5

Ternary operators are also called (mark all that apply)

• Tertiary Operator

• Conditional Operator

• Tripartite operator
