no match at all scenario) then the default case is evaluated. If the case value after default does not match with the variable value (i.e. If you leave out the break statement, the computer will just forge ahead. ![]() But this only happens when the case after default has the same value with variable value. The effect of a break is to make the computer jump to the end of the switch statement. If the case with the matching value as variable’s value is after the default statement, that case statement will execute without the default statement executing even if you put break after default. It can be placed anywhere in the switch block according to the required result. The default statement is meant to execute when there is no match between the values of the variable and the cases. Optional default case: default case value is optional.If a case is matched and there is no break statement mentioned, subsequent cases are executed until a break statement or end of the switch statement is encountered. In this case, it's the switch - because the default switch behavior falls through. Optional Break Statement: Break statement is optional in Java's switch statement. The break applies to the inner-most thing which can be break'd (without a label).de 2020 Switch Statement in Java Java break statement with switch Java switch statement. Primitives are allowed with their wrapper types. Statement outside if block In the program, number < 0 is false. Allowed Types: The Java switch expression must be of int, long, byte, short, enums and String type.A switch works with the primitive types, byte, short, char, and int, their respective wrapper types (Byte, Short, Character, and Integer), enumerated types, and the String type 1. The break statements are necessary because without them, statements in switch blocks fall through: All statements after the matching case label are executed in sequence, regardless of the expression of subsequent case labels, until a break statement is encountered. No duplicates: No two cases in a switch statement should be of same value. Unlike the if/else if/else statement, a switch statement can have a number of possible execution paths.Also, it must be of the same type as switch expression. ![]() No variables: The case value in switch statement must be a literal or constant.Important Points about Java's switch statement: Let’s quickly go through some standard rules for writing switch cases. Now if the values do not match it goes to the next case and follows the same steps and if none of the case values matches the value of the variable, it executes the default statement. Declare the variables that give you an error outside of the switch-case.Next, it goes to Case 1, compare the values, if the value matches it goes on to execute the Statement 1 and then it executes Break statement which brings the switch block to end so no more case testing is done.It starts with the Switch Expression where the variable is placed whose value is to be checked against case values.As it is clear, after the value of day variable matches the case with value 4, all subsequent cases till case 7 are executed until a break statement is encountered in case 7.
