THIS IS MY CODE
i tried to do it but i couldn't

Write a program to read 2 students full names starting with first then fathers name then family , (separated by blanks , e.g : ashelly joe daniel ), then :

• If these two students have same full names display ( These are duplicate names) .
• If they are brothers display (They are brothers or sisters)
• If they are only from same family , display (They are relatives)
• If none of the above , display (May be , they are just friends).

Note : find a way to avoid case-sensitivity, because some will enter names capital or small letters , but for us it should be the same. ( ashelly == ASHELLY)

import java.util.*;
public class MARC
{
static Scanner console = new Scanner(System.in);
public static void main(String [] args)
{

String name1, name2;
int apos1, apos2, rpos1, rpos2;
String first, second, father1, father2, family1, family2;

System.out.println("enter first name: ");
 name1 = console.nextLine();
 
 System.out.println("enter second name: ");
 name2 = console.nextLine();
 
 apos1 = name1.indexOf(' ');
apos2 = name1.indexOf(' ', apos1);
 
 rpos1 = name2.indexOf(' ');
 rpos2 = name2.indexOf(' ', rpos1);
 
 first = name1.substring(0, apos1);
 father1 = name1.substring(apos1+1,apos2+1);
 family1 = name1.substring(apos2);
 
  second = name2.substring(0, rpos1);
  father2 = name2.substring(rpos1+1, rpos2+1);
  family2 = name2.substring(rpos2);
 
 if
 (first.equals(second))
 {
   if 
	(father1.equals(father2))
	
	   if
		(family1.equals(family2))
 System.out.println("These are duplicate names");
 
 
else if
 (first.equals(second))
        if
 (father1.equals(father2))
           if
	 (family1.equals(family2))
	 
	 System.out.println("They are brothers or sisters");


else if 
 (family1.equals(family2))
 System.out.println("They are relatives");
 
 }
 
 else
 System.out.println("May be , they are just friends");
 
 
 }}

 if
 (first.equals(second))
 {
   if 
	(father1.equals(father2))
	
	   if
		(family1.equals(family2))
 System.out.println("These are duplicate names");

use this
if(first.equals(second) && father1.equals(father2) && family1.equals(family2));

else if
 (first.equals(second))
        if
 (father1.equals(father2))
           if
	 (family1.equals(family2))
	 
	 System.out.println("They are brothers or sisters");

use this:
else if
(!first.equals(second) && father1.equals(father2) && family1.equals(family2));

I'll try to write a better code later.

my opinion
change every
console.nextLine();
with
console.nextLine().toLowerCase();

I wrote some code. I think it works.

import java.util.Scanner;

public class CompareStudents {
	
	
	
	public static void main(String[] args) {
		Scanner console = new Scanner(System.in);
		String consoleFirstName;
		String consoleSecondName;
		String consoleFirstFatherName;
		String consoleSecondFatherName;
		String consoleFirstFamilyName;
		String consoleSecondFamilyName;
		
		consoleFirstName = console.nextLine().toLowerCase();
		consoleSecondName = console.nextLine().toLowerCase();
		consoleFirstFatherName = console.nextLine().toLowerCase();
		consoleSecondFatherName = console.nextLine().toLowerCase();
		consoleFirstFamilyName = console.nextLine().toLowerCase();
		consoleSecondFamilyName = console.nextLine().toLowerCase();
		
		Student stud1 = new Student(consoleFirstName, consoleFirstFatherName, consoleFirstFamilyName);
		Student stud2 = new Student(consoleSecondName, consoleSecondFatherName, consoleSecondFamilyName);
		
		stud1.compareStudents(stud2);
		
	}
}

class Student {
	String firstName;
	String fathersName;
	String familyName;
	
	Student(String firName, String fatName, String famName) {
		firstName = firName;
		fathersName = fatName;
		familyName = famName;
	}
	
	public String getFirstName() {
		return firstName;
	}

	public void setFirstName(String firstName) {
		this.firstName = firstName;
	}

	public String getFathersName() {
		return fathersName;
	}

	public void setFathersName(String fathersName) {
		this.fathersName = fathersName;
	}

	public String getFamilyName() {
		return familyName;
	}

	public void setFamilyName(String familyName) {
		this.familyName = familyName;
	}

	public void compareStudents(Student student2) {
		if((this.getFirstName()).equals(student2.getFirstName()) && (this.getFathersName()).equals(student2.getFathersName()) && (this.getFamilyName()).equals(student2.getFamilyName()))
				System.out.println("These are duplicate names");
		else if((this.getFathersName()).equals(student2.getFathersName()) && (this.getFamilyName()).equals(student2.getFamilyName()))
			System.out.println("They are brothers or sisters");
		else if((this.getFamilyName()).equals(student2.getFamilyName()))
			System.out.println("They are relatives");
		else
			System.out.println("May be , they are just friends");
        }
}
