1. String Concatenation Objectives
Concatenate strings into one long string.
Concatenate strings and numbers.
Understand the algebraic rules that define the order in which operators get evaluated.

3. String Literals
A Character string is an object in Java,defined by the String class.
Strings are an important part of computer programming
The string literal is what appears inside the double quotations marks.

4. String Concatenation
The plus operator (+) is also used for arithmetic addition
The function that the + operator performs depends on the type of the information on which it operates
If both operands are strings, or if one is a string and one is a number, it performs string concatenation
If both operands are numeric, it adds them
The + operator is evaluated left to right
Parentheses can be used to force the operation order

5. String Concatenation
System.out.println (“We Present the following facts for your “ “extracurricular edification:”);
Output:
We present the following facts for your extracurricular edification:
System.out.println (“Dialing code for Antartica: “ + 672);
Dialing code for Antartica: 672

6. String Concatenation
System.out.println (“24 and 45 concatenated: “ );
Output:
24 and 45 concatenated: 2445
System.out.println (“24 and 45 added: “ + ( ));
24 and 45 added: 69

7. And then finally…. Output: 100 is equal to one hundred
System.out.println ( “ is equal to one hundred”);
Output:
100 is equal to one hundred
System.out.println ( “ is equal to one hundred ” );
100 is equal to one hundred 5050
