Java’s char Data Type In Java, thechardata type is a 16-bit unsigned integer that represents a single Unicode character. It can hold values ranging from 0 to 65,535. Whilecharitself is not explicitly labeled as signed or unsigned, it can be used to represent both types of values. ...

Built-In Data Types C# provides all the data types that are available in Java, and adds support for unsigned numerals and a new 128-bit high-precision floating-point type. For each primitive data type in Java, the core class library provides a wrapper class that represents it as a Java ...
