Can we add int and byte in Java?

The byte data type in Java is a signed integer based on the two’s complement 8-bit mechanism. It is different from the int data type that uses 4 bytes (i.e., 32-bit to store a number). The values that can be stored in a single byte are -128 to 127.

What is a ByteBuffer in Java?

What is a byte array?

A byte array is simply an area of memory containing a group of contiguous (side by side) bytes, such that it makes sense to talk about them in order: the first byte, the second byte etc..

How do I print a byte array?

How do bytes work in Java?

A byte in Java is 8 bits. It is a primitive data type, meaning it comes packaged with Java. Bytes can hold values from -128 to 127. No special tasks are needed to use it; simply declare a byte variable and you are off to the races.

How do you assign a byte value in Java?

We can assign any int literal that falls in the range of byte to a byte variable. For example, byte b1 = 125; byte b2 = -11; If we assign an int literal to a byte variable and the value is outside the range of the byte data type, Java generates a compiler error.
