1.  Using javap, view the methods of the following classes from the lang package:  java.lang.Object , java.lang.String and java.util.Scanner.  

2.  Compile sample program 2. Type the following command and view the bytecodes. javap -c MyClass

1.  Write a java program to display the system date and time in various formats shown below: 
Current date is  : 31/07/2015 
Current date is  : 07-31-2015 
Current date is  : Friday July 31 2015 
Current date and time is  : Fri July 31 16:25:56 IST 2015

Current time is  :   16:25:56  
Current week of year is : 31 
Current week of month : 5 
Current day of the year is : 212 
Note: Use java.util.Date and java.text.SimpleDateFormat class 

2.  Define a class MyNumber having one private int data member. Write a default constructor to initialize it to 0 and another constructor to initialize it to a value (Use this). Write methods isNegative, isPositive, isZero, isOdd, isEven. Create an object in main. Use command line arguments to pass a value to the object (Hint : convert string argument to integer) and perform the above tests. Provide javadoc comments for all constructors and methods and generate the html help file.

    Slip 3_2: Define a class patient (patient_name, patient_age,
    patient_oxy_level,patient_HRCT_report). Create an object of patient. Handle
    appropriate exception while patient oxygen level less than 95% and HRCT scan
    report greater than 10, then throw user defined Exception “Patient is Covid Positive(+)
    and Need to Hospitalized” otherwise display its information.

    import java.io.*;
    class CovidException extends Exception{
    public CovidException(){
    System.out.println("Patient is Covid Positive and needs to be hospitalized");
    }
    }
    class Patient{
    String name;
    int age;
    double level,hrct;
    public Patient(String name,int age,double level,double hrct)
    {
    this.name=name;
    this.age=age;
    this.level=level;
    this.hrct=hrct;
    }
    public static void main(String[] args)throws IOException
    {
    String name;
    int age;
    double level,hrct;
    BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
    System.out.println("Enter name: ");
    name=br.readLine();
    System.out.println("Enter the age: ");
    age=Integer.parseInt(br.readLine());
    System.out.println("Oxygen level: ");
    level=Double.parseDouble(br.readLine());
    System.out.println("HRCT report: ");

    hrct=Double.parseDouble(br.readLine());
    Patient ob=new Patient(name,age,level,hrct);
    try{
    if(ob.level<95 && ob.hrct>10)
    throw new CovidException();
    else
    System.out.println("Patient Info: \n"+"Name: "+ob.name+"\nAge: "+ob.age+"\nHRCT
    report: "+ob.hrct+"\nOxygen level:"
    +ob.level);
    }catch(CovidException e){
    }
    }
    }
