The Complete Java Developer Course: From Beginner to Master - Arithmetic Operators

This video tutorial covers the basics of working with variables, constants, and data types in Java. It introduces arithmetic operators such as addition, subtraction, multiplication, division, and modulus, and demonstrates their use through a practical example. The tutorial also explains compound assignment operators and increment/decrement operators, providing insights into their syntax and application in coding.

What is the symbol used for the modulus operator in Java?

• #

• &

• @

• %

In Java, what is the result of the expression '10 + 5'?

• 10

• 15

• 105

• 5

What is the term for the elements that an operator acts upon?

• Variables

• Operators

• Constants

• Operands

What is the result of the integer division '15 / 10' in Java?

• 0

• 1.5

• 5

• 1

Which operator is used to add a value to a variable and assign the result back to the variable?

• Compound assignment operator

• Logical operator

• Binary operator

• Unary operator

What is the equivalent expression for 'result += 20'?

• result = result + 20

• result = 20 + result

• result = 20

• result = 20 - result

What is the purpose of the increment operator in Java?

• To add one to a variable

• To subtract one from a variable

• To multiply a variable by two

• To divide a variable by two

Which of the following is a unary operator?

• Increment operator

• Multiplication operator

• Addition operator

• Subtraction operator

What is the result of 'result++' if the initial value of result is 45?

• 46

• 45

• 47

• 44

What is the main difference between unary and binary operators?

• Binary operators are only used in loops

• Unary operators are faster

• Unary operators act on two operands, binary operators act on one

• Unary operators act on one operand, binary operators act on two
