Java vs. C#

foreach

Java
 
Start from Java 5, Java has for each feature
Collection c
for (Object o : c){
 
      
}


The above is equivalent to
for (Iterator i = c.iterator(); i.hasNext(); ) {
       
}



If you don't use Java 5, use the following to replace C# foreach statement.
while (! collection.isEmpty()) {
        Object o = collection.get();
        collection.next();
	...
}


for (int i = 0; i < array.length; i++){
...
}

C#
 
foreach statement is a short-hand of for statement
Readonly feature
foreach (object o in collection){


}


foreach (int i in array){

}
