Datatypes in Java

There are two types :

1) Primitve Datatypes

2) Non-Primitive Datatypes

Let's Discuss Primitive ones in this one :

1. Boolean type

In this datatype it's all about true and false these are used when you want to see whether the given condition is true or false.

class Main { public static void main(String[] args) {

boolean flag = true;

System.out.println(flag);

}

}

It will print true.

2. Byte type

• The byte data type can have values from -128 to 127 (8-bit signed two's complement integer).

• If it's certain that the value of a variable will be within -128 to 127, then it is used instead of int to save memory.

• Default value: 0

• class Main { public static void main(String[] args) {

  byte range; range = 124;

• System.out.println(range);

• }

• }

  It will print 124.

• 3. short type

  • The short data type in Java can have values from -32768 to 32767 (16-bit signed two's complement integer).

  • If it's certain that the value of a variable will be within -32768 and 32767, then it is used instead of other integer data types (int, long).

  • Default value: 0

4. int type

• The int data type can have values from -2³¹ to 2³¹-1 (32-bit signed two's complement integer).

• If you are using Java 8 or later, you can use an unsigned 32-bit integer. This will have a minimum value of 0 and a maximum value of 2³²-1.

• Default value: 0

• 5. long type

  • The long data type can have values from -2⁶³ to 2⁶³-1 (64-bit signed two's complement integer).

  • If you are using Java 8 or later, you can use an unsigned 64-bit integer with a minimum value of 0 and a maximum value of 2⁶⁴-1.

  • Default value: 0
