The Compare() method of Double class is a built-in method in java that compares two specified double values. The sign returned of integer values is the same as that of an integer that will be returned during the function call.

Syntax:
public static int compare(double d1, double d2)
Parameters:
This accept work with two parameters;
- d1: The first Double value that needs to compare.
- d2: The second Double value that needs to compare. ##Return Value: This function will return the following values.
0: if both the numbers are equal.
Negative value: if the value of d1 is less than d2.
Positive value: if the value of d1 is larger than d2.
Example Code:
import java.lang.Double;
public class GFG {
public static void main(String[] args)
{
// Get the two double values
// to be compared
Double d1 = 10d;
Double d2 = 1023d;
// function call to compare two double values
// if d1 and d2 are same
if (Double.compare(d1, d2) == 0) {
System.out.println("d1=d2");
}
//id d1 is less than d2
else if (Double.compare(d1, d2) < 0) {
System.out.println("d1<d2");
}
//if d1 is greater than d2
else {
System.out.println("d1>d2");
}
}
}
Output:
The output of the above program will be d1.
