In Java, int and byte are both primitive types and are used to store numeric values. Both are used to store signed and unsigned values but have different storage ranges. The byte range is -128 to 127, and the int range is -2,147,483,648 to 2,147,483,647. So, clearly, we can ...

Thebytekeyword is used to declare a primitive Java data type containing an integer value in the range of negative128to positive127. A byte is defined as 8 bits in length, regardless of the platform the Java bytecode executes on. Note that byte variables can be cast to and from other nume...
