range of int in java

The range of int type in Java is -2,147,483,648 to 2,147,483,647 because int type uses 32 bits to store data, half of which is used to represent positive integers and half is used to represent negative integers. The int type is widely used for counting, identifiers, and storing integer values, with other integer types of varying ranges and sizes (such as byte, short, and long).

Range of int type in Java

int is one of the most widely used data types in Java. It is used to store integers in the range -2^31 to 2^31-1 (-2,147,483,648 to 2,147,483,647).

Why is the int type limited in scope?

The int type uses 32 bits (4 bytes) to store data. 32 bits can represent 2^32 different values, but since half of them (2^31 values) are used to represent positive integers and the other half are used to represent negative integers, the range of positive integers that can be represented is actually 2^31 -1.

Applications of int type in Java

The int type is commonly used for counting, identifiers and storing integer values. For example:

• Storage the length of the array
• Identifies the index of the loop
• As a method parameter or return value

Comparison of int type with other integer types

There are other integer types in Java, such as byte, short and long, which have different ranges and sizes:

##byte-128 to 127 1 Bytesshort-32,768 to 32,7672 Bytes int ##8 BytesConclusion

Data type	Range	Size
int type is a common type used to store integers in Java and its range is - 2,147,483,648 to 2,147,483,647. For integer values ​​that require a smaller or larger range, you can use the byte, short, or long types.
