Eclipse Memory analyzer
provides various ways of analyzing String from the heap dump. We can get the
details of the String using
1. Open the
Histogram -> Right Click on “java.lang.String” and select the List Objects. We
can get the size by sorting the retained Size ( the memory kept alive by Each
String )
2. If we want to
get the value that is holding by the String, we can get by selecting the String,
right click and “Copy -> Value”. The full value is then copied to the clip
Board.
3. We can also use a
Query to get the details. Select OOL from the Menu as
Enter “SELECT
s.count, toString(s) FROM java.lang.String s” to extract the count property of
the strings.
