1.5.4 Switch Statement

Add this to your Selection project.

NOTES:

• only int and char data types may be used to in the control expression. In this case (month) must be either an int or a char.
• String and enumerated data types will also work
• breaks are required after each case statement or all case statements up to the break will execute

switch Demo

public class SwitchDemo2 { public static void main(String[] args) { int month = 2; int year = 2000; int numDays = 0; switch (month) { case 1: case 3: case 5: case 7: case 8: case 10: case 12: numDays = 31; break; case 4: case 6: case 9: case 11: numDays = 30; break; case 2: if ( ((year % 4 == 0) && !(year % 100 == 0)) || (year % 400 == 0) ) numDays = 29; else numDays = 28; break; } System.out.println("Number of Days = " + numDays); } }
