Java program based on constructor

Program to keep record of height and weight of people.

Code :

import java.io.*;
class Person{
    float height;
    float weight;
    Person(float h,float w){
        height=h;
        weight=w;
    }
    void putPersonData(){
        System.out.print("\nHeight : "+height+" Weight : "+weight);
    }
};
class PersonCount{
    static int count;
    static Person p[]=new Person[10];
    static void showCount(){
        for(int i=0;i<10;i++){
            p[i].putPersonData();
            if(p[i].height>170 && p[i].weight<50){
                count=count+1;            
            }
        }
        System.out.print("\n\nTotal Count (weight<50kg AND height>170cm ) : "+count+"\n");
    }
    public static void main(String args[]){
        p[0]=new Person(173,40);
        p[1]=new Person(170,30);
        p[2]=new Person(168,55); 
        p[3]=new Person(172,55);
        p[4]=new Person(169,55);
        p[5]=new Person(175,70);
        p[6]=new Person(171,45);
        p[7]=new Person(172,55);
        p[8]=new Person(168,55);
        p[9]=new Person(168,65);
        showCount();
    }
}

Output :

Height : 173.0 Weight : 40.0
Height : 170.0 Weight : 30.0
Height : 168.0 Weight : 55.0
Height : 172.0 Weight : 55.0
Height : 169.0 Weight : 55.0
Height : 175.0 Weight : 70.0
Height : 171.0 Weight : 45.0
Height : 172.0 Weight : 55.0
Height : 168.0 Weight : 55.0
Height : 168.0 Weight : 65.0

Total Count (weight<50kg AND height>170cm ) : 2

Program to maintain score card of students.

Code :

import java.io.*;
class Student{
    String name;
    Student(String nm){
        name=nm;
    }
    void putStudentName(){
        System.out.print("\n Student Name : "+name);
    }
};
class Marks{
    Student s;
    int mark1,mark2;
    Marks(String name,int m1,int m2){
        s=new Student(name);
        mark1=m1;
        mark2=m2;
    }
    void putmarks(){
        s.putStudentName();
        System.out.print("\nMark 1 : "+mark1);
        System.out.print("\nMark 2 : "+mark2);
        putAverage();  
    } 
    void putAverage(){
        float t=(mark1+mark2)/(float)2;
        System.out.print("\nAverage : "+t);
    } 
};
class Result{
    public static void main(String args[]){
        Marks m=new Marks("Maverick",80,85);
        m.putmarks();
    }
}

Output :

Student Name : Maverick
Mark 1 : 80
Mark 2 : 85
Average : 82.5
