Thank you comment out if possible Using the switch multiples

Thank you. comment out if possible

Using the switch multiple-selection statement control statements to return the number of days in a month. Each month will be represented by a corresponding integer (1 is January, 2 is February, ...12 is December). There should be separate cases for months with 30 days (September, April, June, and November), months with 31 days (January, March, May, July, August, October, December) and February is its own case. Please help write this java code
