user8565: What is the difference between print( ) and println( )?
I see none when I run a code.

user675: The print("aString") method prints just the string "aString", but does not move the cursor to a new line. Hence, subsequent printing instructions will print on the same line.
The println("aString") method prints the string "aString" and moves the cursor to a new line.
The println() method can also be used without parameters, to position the cursor on the next line.

user29796: print() print which you want but in one line.
For example,
Serial.print("Hello");

Then output in Serial Monitor look like,
HelloHelloHelloHelloHello

println() print same things but in new line.
For example,
Serial.println("Hello");

Then output in Serial Monitor look like,
Hello
Hello
Hello
Hello
Hello


user8420: print() prints whatever you send in.
println() does the same thing, only after using println, anything new that is printed gets printed in next line, I.e. a new line is formed.

user8623: An easy way to see the difference is using Serial.print();/Serial.println();.
print();

will print out whatever you input wherever the cursor currently is. For example:
Serial.print("Test");
Serial.print("Words");

This will print:
TestWords_

The underscore marks where the cursor is (and therefore where the next print command will start). In contrast, the code:
Serial.println("Test");
Serial.println("Words");

will print the following:
Test
Words
_

You can also print multiple statements and then follow with println like so (note the space at the end/beginning of the strings):
Serial.print("These ");
Serial.print("Test");
Serial.println(" Words.");

to get the following output:
These Test Words.
_

You can also use println(); to add a newline character in general. If you would print a variable that doesn't return a newline character, println(); can be used for formatting. Example:
int x = 50;
Serial.print(x);
Serial.println();

This will print:
50
_

Finally, you can add in special characters like a tab \t inside your quotes for formatting. Example:
Serial.println("Test\tTest")

This will return:
Test    Test
