Run static block in java

Question

I have a static block in Java .How can i run it's static initialization block.

I see in this solution How to keep a XMPP connection stable on Android with (a)smack?

https://android.googlesource.com/platform/external/smack/+/master/src/org/jivesoftware/smack/ReconnectionManager.java

static {
try {
    Class.forName("org.jivesoftware.smack.ReconnectionManager");
} catch (ClassNotFoundException ex) {
    // problem loading reconnection manager
}

}

I think, just create constructor in this class – gjman2 Sep 20 '13 at 08:48 — gjman2, Sep 20 '13 at 08:48

when you are calling SmackAndroid.init(Context), it is automatically calling these static classes you can check asmack code for clarification.

if you have any problem related to reconnection then you can check my answer,it is working for me. https://stackoverflow.com/a/23307341/2729665

The static initializer block is run when the class is loaded. If there's nothing else to load the class you can call Class.forName to load it:

try {
    Class.forName("full.name.of.YourClass");
} catch (ClassNotFoundException ex) {
    // installation error? Class not found.
    ex.printStackTrace();
}

how can i know that the ReconnectionManager class is running? – josiland Sep 20 '13 at 19:32
What is ReconnectionManager and how could it be running? If it uses a background thread, you can list the threads with the `jstack` tool or with a debugger. – Joni Sep 20 '13 at 19:39
i use Eclipse as my IDE – josiland Sep 20 '13 at 20:10
Great! Eclipse includes a debugger, doesn't it? – Joni Sep 20 '13 at 20:18
