Constructor Error!

Hi all,
i m totally new with java please help me.
here is my 2 file's code:
-------------------------------------
public class Student {

private String name;
private int rollNo;

private static int countStudents = 0;

public void setName(String name){

this.name= name;
}

public void setRollNo(int rollNo) {
if(rollNo>0) {
this.rollNo = rollNo;
}
else {
this.rollNo = 100;
}
}

public String getName() {
return name;
}

public int getRollNo() {
return rollNo;
}

public static int getCountStudents() {

return countStudents;
}

public Student(){

name = "not set";
rollNo = 100;
countStudents += 1;
}


public Student(String name, int rollNo) {
setName(name);
setRollNo(rollNo);
countStudents += 1;
}

public Student(Student s) {
name = s.name;
rollNo = s.rollNo;
countStudents += 1;
}
public void print() {

System.out.print("Student Name: " +name);
System.out.println("RollNo: " + rollNo);
}
public String toString() {

return "Name: " +name + "RollNO: " +rollNo;
}

public void finalize() {
countStudents -= 1;
}
}
----------------------------------------

public class finalTest {

public static void main(String args[]) {
int numObjects;

numObjects = Student.getCountStudents();
System.out.println("Student Objects: " +numObjects);

Student s1 = new Student("Mike: " +15);
System.out.println("Student Objects: " +s1.toString());

numObjects = Student.getCountStudents();
System.out.println("Student Objects: " +numObjects);

Student s2 = new Student("Smith: ", 13);
System.out.println("student Objects: " +s2); // calling 2 string

numObjects = Student.getCountStudents();
System.out.println("Student Objects: " +numObjects);

s1 = null;

System.gc();

numObjects = Student.getCountStudents();
System.out.println("Student Objects: " +numObjects);

} // End of main
} // End of class

Student.java compiled successfully but when i try to compile finalTest.java
then i facing an error:

D:\tutor\exer>javac finalTest.java
finalTest.java:9: cannot find symbol
symbol : constructor Student(java.lang.String)
location: class Student
Student s1 = new Student("Mike: " +15);
^
1 error
please Help me. Thanks

Maybe you have an typing error, but there is no constructor in your Student class which takes only one String!
Student s1 = new Student("Mike: " +15);

"Mike: "+15 = one String

Perhaps you mean Student s1 = new Student("Mike: " , 15); ??

finalTest.java:9: cannot find symbol
symbol : constructor Student(java.lang.String)
location: class Student
Student s1 = new Student("Mike: " +15);
^
1 error

--------------------Error indicates about this Constructor-----

public Student(Student s) {
name = s.name;
rollNo = s.rollNo;
countStudents += 1;
}
constructor at his place but compiler generate error.

eRaaaa already gave you the solution: you don't have a constructor that takes a single String parameter.

kind regards,

Jos

Code:

---

Student s1 = new Student("Mike: " +15);
Student s2 = new Student("Smith: ", 13);

Even a blind person can see the difference between those two lines of code.
