Nesting if-else Structures So far, you are able to conditionally execute one of two statements based on a sin- gle condition. Sometimes you need to have more than two branches in the flow of your program based on a set of related conditions. This is possible in Java. You know that in the if-else structure, the statement (any valid Java statement) that the program executes if the condition is false follows the else keyword. The key here is any valid Java statement—including another conditional statement. These types of structures are called nested if-else statements. Take a look at the syntax: if (condition1) { java_statements_for_true_condition1; } else if (condition2) { java_statements_for_true_condition2; } else { java_statements_for_false_conditions; } If condition1 is true, the program executes java_statements_for_true_condi- tion1. If condition1 is false, condition2 is tested. You do this by immediately fol- lowing the else keyword with another if conditional statement. If condition2 is true, the program executes java_statements_for_true_condition2. Finally, if neither condition is true the java_statements_for_false_conditions are exe- cuted. Take a look at this quick example, and then move on to the next section where you use apply this concept in an actual program: if (name == “Joseph”) { System.out.println(name + “ is my first name.”); } else if (name == “Russell”) { System.out.println(name + “ is my last name.”); } else { System.out.println(name + “ is not my name.”); } TEAM LinG - Live, Informative, Non-cost and Genuine!Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark.
