Case constants are evaluated from the top down, and the first case constant that matches the switch's expression is the execution entry point. However, the if, then, else statement begins to feel cumbersome when there are a number of choices a program might need to make. Example. Sometimes you will want different cases to use the same code, or fall-through to a common default. Before Java 7, the only means to achieve string based conditional flow was using if-else conditions. 2. Beginning with JDK 7, we can use a string literal/constant to control a switch statement, which is not possible in C/C++. other cases do not need any special processing. In my earlier Java enum examples tutorial, I demonstrated how to declare a simple Java enum, and then how to use an enum with a variety of Java constructs, including a Java switch statement, a for loop, and an if/then statement.. No two case constants in the same switch can have identical values. Well, this is not so bad :) But, a switch is still involved, and the drawbacks remain the same. Java switch case handle multiple conditions. If no break statement used, all the case after entry point will be executed. In Java 7+, we can use a String object in the expression of a switch statement. Java Switch Case. Java switch case String Example Switch Statement in Java. Again, this might change and an extra-processing might be needed. In this case, we can write each value in separate case and only after all cases are written, write down application logic. String in Switch Case in Java. The default case can appear in any order in the switch statement. you know how and where the switch case will be used and what values will enter it. If a default case is not present and the match expression doesn't match any other case label, program flow falls through the switch statement. There are only so many else...if statements you want to add before the code begins to look untidy. If your Java program needs to make a choice between two or three actions, an if, then, else statement will suffice. Sometimes, we want to perform certain action on multiple cases in switch statement. Java enum FAQ: Can you share a Java enum switch example, i.e., how to use an enum with a Java switch statement?. Note that in this example, the cases share the same code block, and that the default case does not have to be the last case in a switch block (however, if default is NOT the last case in the switch block, remember to end it with a break). After all, most Java compilers will generate more efficient bytecode for this implementation than for an if-else-if chain. Java switch case is a neat way to code for conditional flow, just like if-else conditions. But Java 7 has improved the switch case to support String also. If this is the case, I think you are asked to add a default case, because it is an accepted coding style, and it makes your code more readable. Using a string-based switch is an improvement over using the equivalent sequence of if/else statements. Regardless of its order in the source code, it's always evaluated last, after all case …
