Java Program to Calculate Sum of Two Byte Values Using Type Casting
• Difficulty Level : Medium
• Last Updated : 11 Nov, 2020

The addition of two-byte values in java is the same as normal integer addition. The byte data type is 8-bit signed two’s complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The Sum of two-byte values might cross the given limit of byte, this condition can be handled using storing the sum of two-byte numbers in an integer variable.

Example:

```Input:  firstByte = 10, secondByte = 23
Output: Sum = 33

Input:  firstByte = 10, secondByte = 23
Output: Sum = 33
```

Type Casting: Typecasting is simply known as cast one data type, into another data type. For example, in this program, Byte values are cast into an integer.

Approach:

• Declare and initialize the two-byte variable.
• Declare one int variable.
• Store the sum of the two-byte numbers into an int variable.

Below is the implementation of the above approach

## Java

 `// Java Program to Calculate Sum of``// Two Byte Values Using Type Casting`` ` `public` `class` `GFG {``    ``public` `static` `void` `main(String[] args)``    ``{``        ``// create two variable of byte type``        ``byte` `firstByte = ``113``;``        ``byte` `secondByte = ``123``;`` ` `        ``// create int variable to store result``        ``int` `sum;`` ` `        ``sum = firstByte + secondByte;``        ``System.out.println(``"sum = "` `+ sum);``    ``}``}`
Output
```sum = 236

```
