NettetTo get the exact size of a type or a variable on a particular platform, you can use the sizeof operator. The expressions sizeof (type) yields the storage size of the object or type in bytes. Given below is an example to get the size of various type on a machine using different constant defined in limits.h header file − Live Demo NettetJava defines four integer types: byte , short, int , and long . All of these are signed, positive and negative values. Java does not support unsigned, positive-only integers. Many other computer languages, including C/C++, support both signed and unsigned integers. However, Java's designers felt that unsigned integers were unnecessary.
