I was going through http://www.lambdafaq.org/can-lambda-expressions-be-used-to-define-recursive-functions/ and tried to use the following code in a method but it failed to compile:

UnaryOperator factorial = x -> x == 0 ? 1 : x * factorial.apply(x - 1);

Select all Open in new window

Also, I am not able to understand how to call this recursive method to return the factorial of an integer.

There is an entity class defined as DepartmentBase.java which has 200 setter methods and 200 private variables declared for the same.

I'm having Department.java which extends the base class DepartmentBase.java which has few fields as well.

Now i want to create Random values for all the fields in Department.java and return Department object.

I'm not sure how to set all the values of setter which exist in Department and in base class.

Please help me.

Thanks.

I am coding on the Salesforce platform using apex and I'm trying to create a class that will sort a list by two fields using the Comparable interface.

I'm trying to determine how I can sort by two fields so that each product grouping can be sorted by size. The products are clothing items. Each product has a series of sizes. For simplicity, the sizes are S, M, L, XL. What I am trying to achieve is sorting by the size field as well as the product name.

For example, if I have the following products:



I would want them sorted by smallest to largest:

There is a size__c field for each product that holds the size value.

I started by creating a generic sorting utility using the comparable interface to test sorting by product name:

public class GenericSortingUtil {

    public class ObjWrapper implements Comparable {
        
        public sObject obj;
        
        public ObjWrapper() {}

        public ObjWrapper(Sobject obj) {
            this.obj = obj;

        }

        public Integer compareTo(Object compareTo) {
            
            ObjWrapper compareToObj = (ObjWrapper)compareTo;

            if((String)obj.get('Name') > (String)compareToObj.obj.get('Name')) {
                return 1;
            }

while executing spring boot soap example keep getting error like below

Description:

The Tomcat connector configured to listen on port 8081 failed to start. The port may already be in use or the connector may be misconfigured.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 8081, or configure this application to listen on another port.


I tried 8080 as well in application.properties even that did not work

Hi Team,

According to my work, I have to run 7000+ sql statements in DB2 .I have the java code of the same.But by default DB2 java can only run 1338 dynamic statements at one time.
So what I was doing that Split the input data (7000 + ) into mulitiple txt files and run program more than 7 times .Each time I have to change the input path file.

Now  instead of running program 7+ times and manually changing input path everytime,I m trying to dynamically read all the input files from that folder.
Here I am attaching a part of my program only..only the method to read input file.
Below is the code for single input file case. Assume I have files named as a.txt,b.txt,c.txt.....etc.
Text file contains data in the below format:-
----------------------
abc-465747        
dfr-756372
---------------------
Existing code which executes fine  for single input file

declared input file path

static String fileName="C:\\Users\\john\\Desktop\\policies.txt";

Hello everyone!. I am currently using wildfly 12 (on centos 7) in domain mode. I was wondering how to configure it so that the controller runs independently from the nodes. I need this because it has happened to me that for instance node1 failed but it happens to be the controller too and so I don't know how to restart that node without shutting down the entire cluster.
Is there any recommended configuration for this?.
