@KUNAL.SHARMA5724510,
Corrected codes:

STUDENTS: https://ide.codingblocks.com/s/221789
STUDENT_CLIENT: https://ide.codingblocks.com/s/221790

In students class, in the setname method, you didn’t actually set the name. For that just add:

 this.name = name;

I have also highlighted the line in the corrected code. :smile:

#3

i wrote this.name=name, but still there is null

#4

@KUNAL.SHARMA5724510
In students class, setname method, you’ve to write:

 this.name = name;

I have attached the code for the same as well.
If the problem persists please attach screenshots of your output with your code as well.

public class STUDENT { private String name; public String getname() { return this.name; } public void setname(String name) throws Exception { if(name==null||name.equals("")) { throw new Exception(“NAME CANT BE EMPTY OR NULL”); } this.name=name; } public final int RollNo; private static int NoFStudents=0; public static int getNoFStudents() { return STUDENT.NoFStudents; } public static final int MaxStudents=1000; public STUDENT(String name) throws Exception { if(STUDENT.NoFStudents==STUDENT.MaxStudents) { throw new Exception(“LIMIT REACHED”); } this.setname(name); STUDENT.NoFStudents++; this.RollNo=STUDENT.NoFStudents; } }
