i dont no string for servlate

Follow the backslash with another backslash: System.out.println("\\ " \"); will display \ " \ on the screen.
Parsing is very important since the input from the user is not in the form of ints but in a String, therefore, you have to parse the String containing the number into a primitive data type. i.e. String num = "49"; int realNum = Integer.parseInt(num); // puts 49 into realNum;

write a java program to display "Welcome Java" and list its execution steps.
Java doesn't always accept any input as a string it only do that when the input is entered from the " JOptionPane.InputDialog" but it can accept any other data type like integer or short from the console though Scanner class .
The string trim works in Java by trimming white space from the beginning and end of a string. It cleans up the string and makes makes it neater for the users of the program.
".length()". The . length method is inherited from the String class.
