new "for loop " syntax

[Mohit G Gupta]

i have not seen such a syntax before for "for loop"

    
for(Animal animal :a)
{}
for (coffesize cs:coffesize.values())
{}

animal is a class
and coffesize is a enum

i have seen such syntax for "for loop"
for(int a=10;a<10;a++)

why is there only field in the upper "for loop" ?
can anybody explain this

It is the enhanced "for-each" loop of Java introduced since Java 1.5 (Tiger).

[Jesper de Jong]

This is a new feature since Java 5, see: The For-Each Loop

[Moguluri Ravi Kiran]

its for-each loop,used with arrays.
the advantage is, we have no need to use counter variable for iteration.

usage for int array say(arr)

for(int ele:arr)
s.o.p(ele);
