Relationship manager software In Java.

Let's create a simple relationship management software in Java using the console as the user interface. This software will allow you to manage relationships between people by adding, viewing, and searching for relationships. Here's an example implementation to get you started:

```java

import java.util.ArrayList;

import java.util.List;

import java.util.Scanner;

class Person {

    private String name;

    public Person(String name) {

        this.name = name;

    }

    public String getName() {

        return name;

    }

}

class Relationship {

    private Person person1;

    private Person person2;

    private String relationshipType;

    public Relationship(Person person1, Person person2, String relationshipType) {

        this.person1 = person1;

        this.person2 = person2;

        this.relationshipType = relationshipType;

    }

    public Person getPerson1() {

        return person1;

    }

    public Person getPerson2() {

        return person2;

    }

    public String getRelationshipType() {

        return relationshipType;

    }

}

public class RelationshipManager {

    private List<Person> people;

    private List<Relationship> relationships;

    public RelationshipManager() {

        people = new ArrayList<>();

        relationships = new ArrayList<>();

    }

    public void addPerson(String name) {

        Person person = new Person(name);

        people.add(person);

        System.out.println("Person added: " + name);

    }

    public void addRelationship(String person1Name, String person2Name, String relationshipType) {

        Person person1 = findPerson(person1Name);

        Person person2 = findPerson(person2Name);

        if (person1 != null && person2 != null) {

            Relationship relationship = new Relationship(person1, person2, relationshipType);

            relationships.add(relationship);

            System.out.println("Relationship added: " + person1Name + " - " + relationshipType + " - " + person2Name);

        } else {

            System.out.println("Person not found.");

        }

    }

    public void viewRelationships() {

        for (Relationship relationship : relationships) {

            String person1Name = relationship.getPerson1().getName();

            String person2Name = relationship.getPerson2().getName();

            String relationshipType = relationship.getRelationshipType();

            System.out.println(person1Name + " - " + relationshipType + " - " + person2Name);

        }

    }

    public void searchRelationships(String personName) {

        List<Relationship> foundRelationships = new ArrayList<>();

        for (Relationship relationship : relationships) {

            if (relationship.getPerson1().getName().equals(personName)

                    || relationship.getPerson2().getName().equals(personName)) {

                foundRelationships.add(relationship);

            }

        }

        if (!foundRelationships.isEmpty()) {

            System.out.println("Relationships involving " + personName + ":");

            for (Relationship relationship : foundRelationships) {

                String person1Name = relationship.getPerson1().getName();

                String person2Name = relationship.getPerson2().getName();

                String relationshipType = relationship.getRelationshipType();

                System.out.println(person1Name + " - " + relationshipType + " - " + person2Name);

            }

        } else {

            System.out.println("No relationships found for " + personName);

        }

    }

    private Person findPerson(String name) {

        for (Person person : people) {

            if (person.getName().equals(name)) {

                return person;

            }

        }

        return null;

    }

    public static void main(String[] args) {

        RelationshipManager manager = new RelationshipManager();

        Scanner scanner = new Scanner(System.in);

        while (true) {

            System.out.println("Relationship Manager");
