If (x1, y1) and (x2, y2) are two points or coordinates in XP plane, then we can find the distance between them by following mathematical distance formula:

This formula was made from Pythagoras triangle theorem.

Now let’s see how to find distance between two points in Java:
If (x1, y1) and (x2, y2) are two points or coordinates in XP plane, then following java console program shows the distance between them.

## Java Program for Finding Distance between Two Points

```import java.io.*;
class distance
{
int x1,y1,x2,y2,difx,dify;
double d;

void get() throws IOException
{
System.out.print("\n Enter the X part of first point : ");
System.out.print(" Enter the Y part of first point : ");
System.out.print("\n Enter the X part of second point : ");
System.out.print(" Enter the Y part of second point :  ");
}
void display()
{
difx = (x2 - x1) * (x2 - x1);
dify = (y2 - y1) * (y2 - y1);
d = Math.sqrt(difx + dify);
System.out.println("\n Distance between (" + x1 + "," + y1 + ") and (" + x2 + "," + y2 + ") is : " + d + " unit(s) " );
}
public static void main(String p[]) throws IOException
{
distance dis = new distance();
dis.get();
dis.display();
}
}

```

Sample Output:

Enter the X part of first point : 1
Enter the Y part of first point : 4

Enter the X part of second point : 4
Enter the Y part of second point : 0

Distance between (1, 4) and (4, 0) is : 5.0 unit(s).
