# Java program to find out the quadrant in which the given co-ordinate lie ## Quadrant in which the given co-ordinate lie

There are 2 axis (say x and y axis) in a two-dimensional planes. Based on values either positive or negative, a point is decided to lie on which co-ordinate. We need simple if-else statements to write a Java program to find out the quadrant in which the given co-ordinate lie. Generally there are four quadrants.

• Quadrant-1 : both x and y are positive , (+x,+y)
• Quadrant-2 : x is negative and y is positive, (-x,+y)
• Quadrant-3 : both x and y are negative, (-x,-y)
• Quadrant-4 : x is positive and y is negative, (+x,-y)

To better understand see the below example,

1. x=4  and y=5 , Quadrant 1
2. x=-4 and y=5, Quadrant 2
3. x=-4 and y=-5 Quadrant 3
4. x=4 and y=-5  Quadrant 4

## Algorithm

• Step 1:- Start.
• Step 2:- Take inputs for X and Y.
• Step 3:- Check if X and Y are zeroes not if yes then print Origin else check if both X and y are positive Print First quadrant.
• Step 4:- Else if check X is negative and Y is positive print Second quadrant.
• Step 5:- Else if check X and Y both are negative print Third quadrant.
• Step 6:- Else if check X is positive and Y is negative print Fourth quadrant.
• Step 7:- Else print X and Y are at origin.
• Step 8:- End.

Check below Java program to find out the quadrant in which the given co-ordinate lie using above algorithm ## Java Code to find the quadrant in which the given co-ordinate lie:

`import java.io.*; class PREPINSTA{    public static void main (String[] args) {        int x=-4,y=5;        if(x==0 && y==0)        {         System.out.println("Origin");        }        else        {         if(x>0 && y>0)             System.out.println("Quadrant I");            else if(x<0 && y>0)            System.out.println("Quadrant II");         else if(x<0 && y<0)            System.out.println("Quadrant III");         else            System.out.println("Quadrant IV");        }    }}`

## Output:

`Quadrant II`
