switch type

[reubin haz]

Given the following code fragment
switch( x ) {
  case 100 :
   System.out.println("One hundred");break;
  case 200 :
    System.out.println("Two hundred");break;
  case 300 :
    System.out.println( "Three hundred");
     break;
}
choose all of the declarations of x that will not cause a compiler error. [Check all correct answers]
 
a.   byte x = 100 ;
b.
c.   short x = 200 ;
d.
e.   int x = 300 ;
f.
g.   long x = 400 ;
 
  

Answers b and c are correct. But why a is incorrect?

Someone please explain.

Because the maximum value a byte can take is 127, so the switch case which have values greater than 127(e.g 200,300) will give compilation error.
