Question

Task: Modify the Time class and add more methods.

3.1. The class Time (discussed in class) has 2 member methods equals and lessThan. It would be easier for the user to have access to new member methods notEquals, lessOrEquals, greaterThan, and greaterOrEquals. Hint: Don’t start from scratch; make use of the already existing methods.

public boolean notEquals(Time otherTime) {... }
public boolean lessOrEquals(Time otherTime) {... }
public boolean greaterThan(Time otherTime) {... }
public boolean greaterOrEquals(Time otherTime) {... }

3.2. Add 2 more methods named toMilitary and toStandard; they should return a String with the military and standard format for a Time object.

Modify the client for complete testing, including the new methods.

Answer 1

public class Time{

int time;

string s1,s2);

public time(Time t1)

{

time=t1;

s1=" ";

s2=" "

}

public boolean notEquals(Time otherTime)

{

if (time!=otherTime)

return true;

else

return

false

}

public boolean lessOrEquals(Time otherTime)

{

if(time<=otherTime)

return true;

else

return false;

}

public boolean(Time otherTime)

{

if(time>otherTime)

return true;

else

return false;

}

public boolean greaterOrEquals(Time otherTime)

{

if(time>=otherTime)

return true;

else

return false;

}

public string toMilitary(Time otherTime, String str1)

{

time=otherTime;

s1=str1;

s2=" ";

return(otherTime,s1);

}

public string toStandard(Time otherTime, String str2)

{

s2=str2;

return(otherTime, s2);

}

};

import java.io.*

public class Time{

public static void main(String args[])

{

Time t1=new Time("12");

Time t1=new Time("10");

Time str1=new Time("Military");

Time str2=newe Time("Standard");

boolean a,b,c,d;

a=notEquals(t2);

System.out.println(a);

b=lessOrEquals(t2);

System.out.println(b);

c=greaterThen(t2);

System.out.println(c);

d=greaterOrEquals(t2)

System.out.println(d);

String s1,s2;

s1=toMilitary(t2," ");

s2=toStandard(t2, " ");

}

d=greaterOrEquals(t2);
