A switch statement allows a variable to be tested for equality against a list of values. Each value is called a case and the variable being switched on is
Several Actions – The Switch Statement. In addition to the nested if statement Java provides a second method for choosing from many alternative actions.
A case label is the word case followed by a constant integral expression (Strings are allowed if using Java version 7). An integral expression called the switch
JAVA SWITCH STATEMENT. Description. A programming language uses control statements to cause the flow of execution to advance and branch based on changes to
In Java methods usually hold the properties of an object. (A) True. (B) False (B) A default statement is required in every switch statement.

Many beginning programming students have difficulty mastering the C++/Java concept of the switch statement. This paper provides a classroom tested analogy

Java has several types of selection statements: o if Statements if … else statements
Here is a more general explanation of execution of a switch statement: Evaluate the expression to get some value v Three possible cases arise: 1 There is a switch label “case v” Execute the statements in the beginning with the first one following that switch label 2 There is no switch label “case v” and there is a default switch label
Switch Statements The switch statement is another type of conditional It is similar to an if-statement but in some cases it can be more concise You don’t have to think about the exact meaning just yet as we will get to it in the example below: We’re going to use this series of status enums (shown in Example 1) from my article about
You use the switch statement in Java to execute a particular code block when a certain condition is met. switch (expression) { case 1: // code block break; case 2: // code block break; case 3: // code block break; default: // code block } Above, the expression in the switch parenthesis is compared to each case.
Basically, the expression can be a byte, short, char, and int primitive data types. It basically tests the equality of variables against multiple values. Note: Java switch expression must be of byte, short, int, long (with its Wrapper type), enums and string.
In simple words, the Java switch statement executes one statement from multiple conditions. It is like an if-else-if ladder statement. It provides an easy way to dispatch execution to different parts of code based on the value of the expression. Basically, the expression can be a byte, short, char, and int primitive data types.
