Well, you don't convert a String to a StringPool. StringPool is a collection of strings managed by the JVM. You can, however, request a string to be included in the pool by requesting the VM to do so using intern() method of the String object if it has not been created as a literal (otherwise it is already there)

   String test= "test".append("Case").append("String");
   test.intern(); //string "testCaseString" will be interned

   String check= "InternString";
   check.intern(); //redundant as the string was already interned in the above creation statement

If your object is really new String("abc"), then you should just use "abc" instead of creating a new string and interning this one. "abc" is interned anyway, as all string literals are.

I.e., the below boolean operation will be true

"abc" == new String("abc").intern()

   String str=  new String("abc").intern() // calling intern() will add the String object to the String pool.
