This article mainly introduces the relevant knowledge of "what is the execution process of java switch statement". The editor shows you the operation process through an actual case. The operation method is simple, fast and practical. I hope this article "what is the execution process of java switch statement" can help you solve the problem.

1. Grammar

Switch (constant) {case expression 1: statement aspect 1 switch breakscape case expression 2: statement aspect 2: politics breakstor.default: statement aspect nactiveness breakbreak;}

2. Execution process

(1) case uses its own expression to see if it matches the constant. If there is a match, the statement body is executed, otherwise the default statement is executed.

(2) case performs similar parallel operations, not sequential operations. So the value of each expression cannot be the same. Which case matches the constant will execute its own sentence and will not look for other case sentences.

3. Examples

Int I = 10 switch (I) {case 10:System.out .println ("A"); / / break;case 5:System.out .println ("B"); / / break;case 7:System.out .println ("C"); / / break;default: System.out .println ("error"); break;} / / print the result: this is the end of A B C error's content on "what is the process of java switch statement execution".
