Java variables: The java variables are the containers to hold a value during the program execution. The variables can be declared in different data type according to the need. The variables are names to some memory location and these memory locations can hold values. The variables can have the data type, integer, character, float, double and so on. If a variable is declared as “int” data type, then this variable will hold an integer value. Likewise, “float” data type variable will hold a floating point value and so on. The value of a variable may change when the program start the execution if the change is mentioned in the program code. “System.out.println” statement: The “System.out.println” is a java statement used to print its argument into the “System.out”. The “System.out” is generally stdout. The one difference from “print()” method is “println()” method creates a newline after printing its arguments on the monitor. This method is used when the user need output in separate lines. Example: //how to use println System.out.println(“Hello!”); The above statement will print “Hello!” on the monitor.
