Learn Java Tutorial 9 Difference between println and print function смотреть онлайн

This tutorial is made for learning about the Difference between println and print function of Java Programming Language.

Println - adds a new line to the end of the line. Puts the cursor on a new line

Print - prints out the line and the cursor is placed directly after it

Difference between print() and println()

The only difference between the print() and println() methods is that the println() statement positions the cursor onto the next line after printing the desired text while the print() method leaves the cursor on the same line. The difference is evident when we print text using more than a single statement. The following statements use the print() method.

System.out.print("Hello ");
System.out.print("World ");

The output of these statements would be:

Hello World

After printing the word 'Hello', the cursor remained on the same line. That is why 'World' was also displayed on the same line. If we use the println() statement, the output would be different.

System.out.println("Hello ");
System.out.println("World ");

The output would be

Hello
World

After printing the word 'Hello', the cursor moved to the next line. That is why the word 'World' was printed on a new line.

Concatenation using + operator

We can use the concatenation operator + to join two or more Strings and print them. To print the value of a variable, we simply state it within the parentheses. Look at the following code for example:

int a=1;
String s = "World";
System.out.println(a+" "+"Hello "+s+"!");

The output would be

1 Hello World!

The expression within the parentheses is evaluated from left to right and particular care has to be taken when including variables that store integers, real numbers and characters.
