the jdk1.5 for loop is used for read only purpose and not the changes the data or values.

for each loop is used for iterating purpose, an advanced version of old for loop..

Hi Geet,

In below for loop

for(Dog a og){
a=new Dog();
}//but if i use this one then the output is null

you are not initialising dog array, but you are assign the Dog object to the variable 'a'. thats why displaying 'null'.

if you want to initialse dog array you have modify like this

int i = 0;
for(Dog a og){
a=new Dog();
dog[i++] = a;
}
 
All that thinking. Doesn't it hurt? What do you think about this tiny ad?
