📘 Step Learning

In this program you will learn about byte datatype in java programming language. Here you will learn how to declare a byte data type in your class.

💻 Program Code

 public class Sample {

   public static void main(String []args) {
      // this is declaration and initialization of variable a
	  // datatype is byte 
	  byte a = 100;  
	  // this is declaration and initialization of variable b
	  // datatype is byte 
      byte b = -50; 
      System.out.println(a); // it will print a variable 
      System.out.println(b); // it will print b variable 
   }
}

🖥 Program Output

100
-50

📘 Explanation

Byte data type is an 8-bit signed two's complement integer
Minimum value is -128 (-2^7)
Maximum value is 127 (inclusive)(2^7 -1)
Default value is 0
Byte data type is used to save space in large arrays, mainly in place of integers, since a byte is four times smaller than an integer.
Example: byte a = 100, byte b = -50

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
