LinearPerson.java
please help me the JAVA program
A LinearPerson lives on a number line. At any time, he or she has a position, such as 0 or 3 or -5. He or she can move one position at a time. He or she has a direction of movement. So if a LinearPerson is moving right and is at position -3, the new position will be -2. If a LinearPerson is moving left and is at position -3, the new position will be -4. The following describes the LinearPerson class: You should decide the instance variables needed for LinearPerson. Overloaded constructors: a no-argument constructor that sets the current position at 0 and the current direction as "to the right." a constructor that takes one int as a parameter; the parameter represents the initial position of the LinearPerson methods: public void turn()//changes the direction of the LinearPerson (right to left, or left to right) public void move()//moves the LinearPerson one position in his or her current direction public int getPosition()//returns the current position of the LinearPerson As an example LinearPerson sophie = new LinearPerson();//sophie is at position 0, moving right sophie.turn();//sophie is at position 0, moving left sophie.move();//sophie is at position -1, moving left sophie.move();//sophie is at position -2, moving left sophie.turn();//sophie is at position -2, moving right sophie.move();//sophie is at position -1, moving right Create a class LinearPersonPairthat creates two LinearPerson objects, one using the no-argument constructor, the other object should be created at a given location. The program moves the objects in various directions and prints their final locations.Explanation / Answer
public class LinearPerson
{
private int curr_pos;
private char curr_dir;
LinearPerson()
{
curr_pos=0;
curr_dir='r';
}
LinearPerson(int p)
{
curr_pos=p;
curr_dir='r';
}
public void turn()
{
if(curr_dir=='r')curr_dir='l';
else curr_dir='r';
}
public void move()
{
if(curr_dir=='r')curr_pos=curr_pos+1;
else curr_pos=curr_pos-1;
}
public int getPosition()
{
return this.curr_pos;
}
}
public class LinearPersonPair
{
public static void main(String args[])
{
LinearPerson a=new LinearPerson();
LinearPerson b=new LinearPerson(3);
a.move();
b.move();
a.turn();
b.turn();
a.move();
b.move()
System.out.println(a.getPosition()+" "+b.getPosition());
}
}
