Course Introduction：In the Java programming language, the process of converting one data type to another is called type conversion. Sometimes, it is necessary to convert an integer data type to a byte data type. However, it is crucial to understand the scope of the byte data type. The byte data type is an 8-bit signed two's complement integer with a minimum value of -128 and a maximum value of 127. If the integer value is within this range, a direct type conversion to a byte variable is possible. However, if the integer value is outside this range, an alternative approach is required. One way to do this is to use the modulo operator to convert an integer value to a value in the range of a byte data type, and then type-cast it to a byte variable. This article aims to elaborate on converting integer data type to byte number through type conversion in Java
