Java 8 - Primitive type Functional Interface for Supplier

-
Primitive type Functional Interface for Supplier:
1. IntSupplier
public int getAsInt();
2. LongSupplier
public long getAsLong()
3. DoubleSupplier
public double getAsDouble()
4. BooleanSupplier
public boolean getAsBoolean()

class Test
{
public static void main(String[] args)
{
IntSupplier s=()->(int)(Math.random()*10);
String otp="";
for(int i =0;i<6;i++)
{
otp=otp+s.getAsInt();
}
System.out.println("The 6 digit OTP: "+otp);
}
}

Output: The 6 digit OTP: 035716

How to set Java Object into JaxBElement ? * In JaxBElement we are having setValue(T t) method. this will help us to solve this problem. * java.xml.bind.JAXBElement.setValue() Eg.

Pipeline: * Group of jobs executed in Stages. * All of the jobs executed in parallel in stage. * if all jobs succeed, pipeline move to next stage. * if any one job failed, next stage is not executed. Types of Pipeline: * CI Pipeline build and test stages defined (.gitlab-ci.yml) * Deploy Pipeline: define in .gitlab-ci.yml. Flow of deploying code to server thru various stages. * Project Pipeline: Specially for microservices. Cross project CI depencies, triggered via API. GitLab Architecture: * GitLab Server and atleast one GitLab Runner. * Runner is the one will start the job. * Project Setting -CICD - * GitLab Runner is automatically provided by GitLab Server. * We can also configured our own runners. Why GITLab CI: * Simple Architecture * Docker first approach. * Pipeline as code. * Merge request with CI support. Eg. Build file location: /builds/kumarvinothjoseph/spring-boot-integration-watch-directory/target/spring-integration-moni...
