The parseLong() is the static … Java developers included these data types to maintain the portability of java as the size of these primitive data types do not change from one operating system to another. This is known as implicit type casting or type promotion, compiler automatically converts smaller data type to larger data type. We can also convert int to long using valueOf() method of Long wrapper class. In many ways the need to consider the "type" of data is something of a throwback to the early days of … Although Java has no unsigned long type, you can treat signed 64-bit two's-complement integers (i.e. Active 21 days ago.
