We can iterate through collection easily by pressing Ctrl+Alt+T, 
And then I wanted to create such template for iterating through map: I wrote these lines to template text box:
for (Map.Entry<$ELEMENT_TYPE$> $VAR$ : $SELECTION$.entrySet()) {
$END$
}
Now it is generating these codes:
HashMap<String,Object> map=new HashMap<String,Object>();
for (Map.Entry<Object> objectEntry : map.entrySet()) {
}
Map.Entry<Object> should be Map.Entry<String,Object>. I cannot find a way to introduce variable correctly. How can I do that?

Use the forEach() method to iterate over a Map object. The forEach method takes a function that gets invoked for each key/value pair in the Map , in insertion order. The function gets passed the value, key and the Map object on each iteration.
Using forEach(action) method : In Java 8, you can iterate a map using Map. forEach(action) method and using lambda expression. This technique is clean and fast.
It is easier if you just type iter and then Tab.
You will get a drop-down and there you can choose map.entrySet() and it will give you:
for (Map.Entry<String, Object> stringObjectEntry : map.entrySet()) {
}
To view a list of live template available: Ctrl + J and then Tab.
From there you will have list of live template, iter (for each loop) will be on the list.
