![]() ![]() Statements to executed when none of the cases is trueĭespite being optional, the break statement is mostly used with switch case in Java. An optional default statement is written at the end. Any number of case statements can be added to the code Statements to executed in case of value 2 is true Statements to executed in case of value 1 is true Case Sensitive Comparison: The switch statement compares the String object in its expression with the expressions associated with each case label as if it were. ![]() From JDK7, it can also be used with enumerated (Enum) data types in Java, the String class and Wrapper classes.įollowing is the Syntax of switch case in Java: switch(variable or an integer expression) The expression can be a byte, short, char, and int primitive data types. It is a multi-way branch statement that provides paths to execute different parts of the code based on the value of the expression. The switch case is very commonly used in Java. A Switch case statement is one of the conditional statements commonly found in almost every other programming language. In Java, the switch statement is used for executing one statement from multiple conditions. A code is mainly comprised of series of conditions and their possible outputs in either case. The conditions and logical statements are an integral part of any program. With JDK7, the switch case in java works with the string and wrapper class and. The given expression can be of a primitive data type such as int, char, short, byte, and char. Based on the value of the expression given, different parts of code can be executed quickly. Here, the size variable is assigned with the value Large. Since the value matches with 44, the code of case 44 is executed. The variable is compared with the value of each case statement. Switch expression must be a constant value: The switch statement or switch case in java is a multi-way branch statement. In the above example, we have used the switch statement to find the size.Few characteristics of switch case in Java.Do we use break statement after default?. ![]()
