hey @shubhij
Make constructor of Employee class
correct code
import java.util.*;

public class Main {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
int x = sc.nextInt();
int n = sc.nextInt();
Employee obj[] = new Employee[n];
for (int i = 0; i < n; i++) {
String name = sc.next();
int sal = sc.nextInt();
obj[i]=new Employee(sal, name);
}
for (int i = 0; i < n; i++) {
System.out.print(obj[i].name);
System.out.print(obj[i].salary);
}

}

private static class Employee {
	int salary;
	String name;

	public Employee(int c, String d) {
		salary = c;
		name = d;
	}
}

}
