Matching pattern for the switch in java is a pattern where we examine a variable and depending on its value; we execute the block of code that corresponds to it.

Normally, the switch statement chooses one of several possible courses of action based on the value of an integer expression. The matching pattern for the switch in java executes a block of code depending on the value of an object under test. For example, if you want to test your algorithm against the hardest possible pattern, you can create an array with all possible patterns and generate random instances of that array. However, this is not feasible in many situations (for instance, when there are more than 2^64 possible patterns).

Switch statements in Java are very similar to those in C and other languages. You can have an optional case label, followed by one or more when labels and a default label at the end. But unlike C, the Java switch statement doesn't allow fall-through; jumping to another case label is not allowed. The new version, which was introduced with Java 7, supports a "matching" clause that can be used instead of case values.

Java latest version switch case statements can be written in different ways. It’s easy to confuse yourself if you are not careful. The first method is the traditional switch case statement, where we have several case labels, followed by a block of code for every case.

Here is the syntax:

switch (obj) { case 1: //do something case 2: //do something case 3: //do something //etc…} Eiliana is a freelancing platform that connects companies and individuals with the top talent in the world.
