Question: How Do You Check Two Values On A Switch Case?

Can we use char in switch case in Java?


The variable used in a switch statement can only be integers, convertable integers (byte, short, char), strings and enums.

The value for a case must be the same data type as the variable in the switch and it must be a constant or a literal..

How do you put multiple conditions in a switch case in Java?

Java switch case handle multiple conditions In this case, we can write each value in separate case and only after all cases are written, write down application logic. For example, in given program all odd tokens will be handled by first switch case, and even tokens will be handled by second switch case.

Can you use or in switch case?

The switch-case construct is pretty similar to an if-else statement, you can use the OR operator in an if however.

How do you write a switch case in an algorithm?

A general syntax of how switch-case is implemented in a ‘C’ program is as follows: switch( expression ) { case value-1: Block-1; Break; case value-2: Block-2; Break; case value-n: Block-n; Break; default: Block-1; Break; } Statement-x; The expression can be integer expression or a character expression.

Can Switch case be used for strings?

Strings in switch Yes, we can use a switch statement with Strings in Java. … The expression in the switch cases must not be null else, a NullPointerException is thrown (Run-time). Comparison of Strings in switch statement is case sensitive.

How many cases can you have in switch statement?

257 caseStandard C specifies that a switch can have at least 257 case statements. Standard C++ recommends that at least 16,384 case statements be supported! The real value must be implementation dependent.

Why is String class considered immutable?

The string is Immutable in Java because String objects are cached in String pool. … Another reason of why String class is immutable could die due to HashMap. Since Strings are very popular as HashMap key, it’s important for them to be immutable so that they can retrieve the value object which was stored in HashMap.

Can I use string in Switch Case C++?

Indeed, the switch/case statement works only on integral values (an enum, an integral type such as char and int, or an object type with implicit cast to an integral type). … But strings aren’t of integral types!

How do you check multiple conditions in a switch case?

SWITCH STATEMENT: check multiple conditions using AND operator? default: A: ($val>=2 && $val <= 4) A: ($val>=2 && $val <= 4) A: ($val>=2 && $val <= 4) B: ($val>=2 && $val <= 5) D: ($val>=3 && $val <= 6) default:

How do you pass multiple values in a switch case?

Second, the only way to use switch with multiple variables is to combine them into one primitive (string, number, etc) value: var stateA = “foo”; var stateB = “bar”; switch (stateA + “-” + stateB) { case “foo-bar”: … … }

How do you check the condition of a switch case?

Here the mark is defined as 100 and when switch statement is executed, the condition will be checked as mark <=35. true => (100 <= 35) - this will give the result false. ... case mark >=36 && mark <= 60. true === (100 >=36 && 100 <= 60) ... case mark >= 61 && mark <= 80. ... case mark >= 81.
