Display Variables – Java Print Variables
Use println( ) method is usually used to display whatever you can put inside.
If you want to combine both text and a variable, use the + character, and text always comes in these ” “:
Code Example:
public class first {
public static void main(String[] args) {
/* Learn How to Use Println
Println prints every println in different line
*/
String name = "Hanuman!";
System.out.println("Name of the person is: " + name);
System.out.println("Name of the person Writing 2nd time: " + name);
/* Learn How to Use Print
Print prints every print in same line
*/
String name1 = "Sita!";
System.out.print("Name of the person is: " + name1);
String name2 = "Ram!";
System.out.print(" Name of the person is: " + name2);
}
}
The output of the above Code:
PS C:\Users\Priyanka\Documents\java> javac first.java
PS C:\Users\Priyanka\Documents\java> java first
Name of the person is: Hanuman
Name of the person Writing 2nd time: Hanuman
Name of the person is: SitaName of the person is: Ram
PS C:\Users\Priyanka\Documents\java> javac first.java
PS C:\Users\Priyanka\Documents\java> java first
Name of the person is: Hanuman
Name of the person Writing 2nd time: Hanuman
Name of the person is: Sita Name of the person is: Ram
PS C:\Users\Priyanka\Documents\java> javac first.java
PS C:\Users\Priyanka\Documents\java> java first
Name of the person is: Hanuman!
Name of the person Writing 2nd time: Hanuman!
Name of the person is: Sita! Name of the person is: Ram!
PS C:\Users\Priyanka\Documents\java>
The output of the above Code with Image:
Note: You can also use the + sign or character to add multiple variables or variables to another variable:
Code Example:
public class first {
public static void main(String[] args) {
/*
* Learn How to Use Println
* Println prints every println in different line
*/
StringName1 = "Ram ";
StringName2 = "Sita";
StringName = Name1 + Name2;
System.out.println("Best Name in the World: " + Name);
/*
* Learn How to Use Print
* Print prints every print in same line
*/
Stringname1 = "Sita!";
System.out.print("Name of the person is: " + name1);
Stringname2 = "Ram!";
System.out.print(" Name of the person is: " + name2);
}
}
Output Result:
PS C:\Users\Priyanka\Documents\java> javac first.java
PS C:\Users\Priyanka\Documents\java> java first
Best Name in the World: Ram Sita
Name of the person is: Sita! Name of the person is: Ram!
PS C:\Users\Priyanka\Documents\java>
Output with Image:
When you use numeric values, the + character or sign works as a mathematical operator. Notice how we have used int (integer) variables here:
Code Example:
public class Main {
public static void main(String[] args) {
int x = 41;
int y = 71;
System.out.println(x + y); // Print the value of x + y
}
}
Output:
In the example above, you can see:
- x stores the value 41.
- y stores the value 71.
- Then we use the println() method. It will display the value of x + y, which is 112.
