Java: how to turn local references created in for loop into global references?

How to create local references created in for loop into global references? The following code wont compile:

Also, in real project, the number of t's and type of t's are data driven (I'm looping through a map of maps to make decision), so I cannot specify t before starting for loop.....

public class TestLocal{
  public static void main(String [] args){

  for (int i=1; i<1; i++){
    TestLocal t=new TestLocal();
   }
   System.out.println("This is the new object:  " + t );
 }
}

How could I make t accessible from outside for loop?

more code

Note:

1)test has many values, and what instance to create depends on its value.

2) since I'm looping through a map of maps which are data driven, t开发者_开发百科he number of instances to be created depend on the number of inner maps......

                        for (int i=0;i<sortedMap.size();i++){
                           ArrayList<Object> a = new ArrayList<Object>(sortedMap.keySet());
                           Object o=a.get(i);
                           HashMap m=(HashMap)sortedMap.get(o);
                           int test = ((Number)m.get("textType")).intValue();
                          if (test==3){
                           System.out.println("all together: " + sortedMap.size() + "each element is:  " + o + " value: " + m.get("textType"));
                           String mytest = (String)m.get("text");
                           ChapterAutoNumber chapter1 = new ChapterAutoNumber(mytest);
                        }

There's no such thing as a "local reference" or a "global reference". You're just trying to access a variable without it being in scope. You want something like:

TestLocal t = null;
for (int i=1; i<1; i++) {
    TestLocal t=new TestLocal();
}
System.out.println("This is the new object:  " + t );

Note that this will print null though, because you're not actually going to run the loop body (because 1 is not less than 1).

If you want to collect the objects created in the loop, a list may be more appropriate:

List<TestLocal> list = new ArrayList<TestLocal>();
for (int i = 0; i < 10; i++) {
    list.add(new TestLocal());
}
// Now access the objects via list

Put them in a collection. For example a Set

Set<TestLocal> set = new HashSet<TestLocal>();

for (..) {
  TestLocal t = new TestLocal();
  set.add(t);
}

Then you can iterate your instances:

for (TestLocal t : set) {
 // access each instance
}

If you want just one instance to be accessible outside, then simply define it outside:

TestLocal t = null;
for (..) {
  t = new TestLocal();
}
