Java SE (Java Platform, Standard Edition)

hello,

I need one help sir.

If I am clicking one item(IPAddress) from JList , and click Connect button, then the selected item from the list ie. that IP address connects with its corresponding device through SNMP.

For this,

I create an object ,

Object firstSel = jList2.getSelectedValue();

but in snmp , the object is not accepted. it requirs String.

How can I convert Object to string in java.

If I am using string for getSelectedValue() , it gives error.

that is ,

String firstSel = jList2.getSelectedValue();

error is,
mainFrame.java:582: incompatible types

how can i fix this problem.
Thanks in advance.
