What is difference between if statement and switch statement ?
Answer : Please see below :
if statement | switch statement |
| if can be used to test multiple conditions | switch cannot be used to test multiple conditions |
| multiway execution is not available | switch provides multiway execution |
| if statement is not good choice if number of condition is more. Because switch uses index mapping on variable choice to the corresponding solutions | switch statement is preferable if number of test conditions are more |
| for multiple condition if statement is not developer friendly and including maintenance of code could be tough | switch is generally more dense for multiple condition |
| in if statement you can evaluate complex expressions | switch evaluate expression using constant |
| if statement accepts all data types | switch statement accepts only primitive types as key and constants for cases |
| Performance of if statement will be slow for multiple condition | Performance is faster because switch uses index mapping |
