What are the three basic types of data?

Answer 1

Java has a total of 8 primitive data types

# byte: The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). # short: The short data type is a 16-bit signed two's complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive) # int: The int data type is a 32-bit signed two's complement integer. It has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647 (inclusive). # long: The long data type is a 64-bit signed two's complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive). # float: The float data type is a single-precision 32-bit IEEE 754 floating point. # double: The double data type is a double-precision 64-bit IEEE 754 floating point. # boolean: The boolean data type has only two possible values: true and false. # char: The char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65,535 inclusive). In addition to the eight primitive data types listed above, the Java programming language also provides special support for character strings via the java.lang.String class. Enclosing your character string within double quotes will automatically create a new String object;

For ex: String name = "Rocky"; would create a new String object of name "name" and holding an initial value "Rocky"
