Operators in java : Operators are special symbols that perform specific operations on one or more operands, and then return a result. Java provides a rich set of operators to
Floating point literals : By default every floating point literal is double type. So, we cannot assign floating point literal to float type directly. To assign floating point literal to
Boolean literals : Possible boolean literals are ‘true’ and ‘false’. Boolean literals are case sensitive. boolean b = true; // fine compilation boolean b = True; // causes compiler error
Character literals : To hold characters, we use char data type. The characters that are assigned to char data type are called character literals. Example : char a = ‘s’
Integer literals : Values that we can assign to integer data types ( byte , short , int, long ) are called integer literal . All positive and negative numbers
A constant value that can be assigned to variable is called literal. For example : int a= 10. Here, 10 is a literal. The following are different types of literals
Single precision : To represent IEEE standard single precision float type we need 32 bit word. First bit (left most bit) is the sign bit. Next eight bits are Exponent
Floating point data types can hold fraction numbers. float, double comes under Floating point data types category. Let’s see each one in detail . float : float size is 32
boolean : To assign logical values, java provided boolean data type Possible values we can assign to boolean type are true and false Both true and false are case sensitive
In java, char is used to hold the character data. In C & C++ we can use ASCII characters only. To hold all the ASCII characters 1 byte (1 byte
