Java Output:

In this chapter, we will learn to print variables and values.

We use,

System.out.println();

To print output to the screen.

The value/variable we want to print is put inside the parentheses ().

Next, we will look at an example of it.

Example: Print Numbers

● copy the below code and paste it your java compiler.

class Main { 

public static void main(String[] args) { 

System.out.println(5); 
          
System.out.println(5.6); 
          
System.out.println(-15.6); 

} 
} 

/*Output:
5
5.6 
-15.6 

Note: System. out.println() prints a new line (enter) at the end. That’s why each number is printed in a new line. */

Example: Print Text

● copy the below code and paste it your java compiler.

● To print a text, it must be inside double quotes.

class Main { 

public static void main(String[] args) { 

System.out.println( “Learn Java .”); 

System.out.println(“Share the website if you like it.”); 

} 
}

/*Output:

Learn Java from Programiz. 
Share the website if you like it. */

Example: Print sentences

● the code below prints the pie value, which is included in the System.out.println( " " + pie )

● the code below prints the pie value, which is included in the System.out.println( " " + pie )

class Main { 

public static void main(String[] args) { 

double pie = 3.1415; 

System.out.println("I am " + "pie."); 
System.out.println("\nMy value is: " + pie); 
} 
} 

/*Output: 
I am pie. 
My value is: 3.1415 */
