System.out.println("text");

//You can use any variable type, not just strings, although

#Here are few methods to print data.
1) System.out.println(); --> move the cursor on new line
2) System.out.print(); --> on same line
3) System.out.printf(); --> on same line
java providing build-in class called System, and System class is having
build-in object called out, this object is attached to the monitor or console,
means a static object.
and the out object having the methods called println, print, and printf, etc.
print method takes parameters or values, means parameter in different type.
print method support all data type like --> int, float, char, String, double,
long, etc.
NOTE : if method can have same name but different in parameters called
overloaded method, so print method is also a overloaded method but passing
different in parameters.
###############################################
IMPORTANT NOTE :
suppose x and y are two variables and it contains int type value as 5 and 6.
Then how the print method will works ?
.........................................
System.out.println("Hello " + x + y);
First string is concatenate with x and then concatenate with y
the output we get --> Hello 56.
.......................................
In Other way ----------
.......................................
System.out.println(x + y + " Hello");
First x and y will add and then concatenate with string.
the output we get --> 11 Hello
......................................
#########################################
if to achieve the first way to add x and y use parentheses () arount x and y
like (x + y), now it add and then concatenate
System.out.println("Hello " + (x + y));
output --> Hello 11
/* For this function, let me use the example I have used
just now. You should be able to see the difference right away:
*/
public class Main{
public static void main(String[] args) {
System.out.print("Hello World!");
System.out.print("Welcome to freeCodeCamp");
}
}
/* Here, you see that I used print instead of using println
like I did earlier. The print doesn't add the additional
(new line character) after executing the task in it.
This means that you will not get any new line after executing
any print statement like above.
*/
// The output will be like this:
// Hello World!Welcome to freeCodeCamp
/* If you want, then you can also solve this issue using
like below:
*/
public class Main{
public static void main(String[] args) {
System.out.print("Hello World!
");
System.out.print("Welcome to freeCodeCamp");
}
}
/* This time, the
will work as the new line character and
you will get the second string in a new line.
The output is like below:
*/
// Hello World!
// Welcome to freeCodeCamp
/* You can also print the two strings using only one print
statement like below:
*/
public class Main{
public static void main(String[] args) {
System.out.print("Hello World!
Welcome to freeCodeCamp");
}
}
// The output will be the same this time:
// Hello World!
// Welcome to freeCodeCamp
