Java 11 Programming for Beginners 2.4: Using Primitive Types

This video tutorial covers the basics of Java primitive types, including their storage and limitations. It explains overflow and underflow concepts and demonstrates how to calculate interest using Java programming. The tutorial introduces while loops for control flow and provides techniques for printing and debugging. It concludes with a simulation of payment adjustments and handling infinite loops.

What is the primary focus of this video tutorial?

• Java GUI development

• Calculated steps, primitive types, and loops

• Basic Java syntax

• Advanced Java networking

Which Java primitive type is used to store true or false values?

• int

• char

• byte

• Boolean

What is the range of values that a byte can store in Java?

• -128 to 127

• 0 to 255

• -32768 to 32767

• 0 to 65535

What happens when a value exceeds the storage capacity of a primitive type in Java?

• The program crashes

• The value is truncated

• The value is stored as a string

• An overflow occurs

What is the result of an underflow in floating-point calculations?

• The value becomes negative

• The value becomes zero

• The value is rounded to the nearest integer

• The value becomes infinite

Which data type should be used for precise decimal calculations in Java?

• char

• double

• int

• float

What is the purpose of the 'var' keyword in Java?

• To create a constant variable

• To automatically infer the variable type

• To declare a global variable

• To declare a variable with a fixed type

What is the function of a while loop in Java?

• To execute a block of code only if a condition is false

• To execute a block of code a fixed number of times

• To execute a block of code as long as a condition is true

• To execute a block of code at least once

How can you prevent an infinite loop in Java?

• By using a continue statement

• By using a return statement

• By ensuring the loop condition eventually becomes false

• By using a break statement

Which operator is used for compound assignment in Java?

• --

• ++

• ==

• +=
