# Java.math.BigDecimal.compareTo() Method

## Description

The **java.math.BigDecimal.compareTo(BigDecimal val)** compares the BigDecimal Object with the specified BigDecimal value.

Two BigDecimal objects that are equal in value but have a different scale (like 2.0 and 2.00) are considered equal by this method.

This method is provided in preference to individual methods for each of the six boolean comparison operators (<, ==, >, >=, !=, <=).

The suggested idiom for performing these comparisons is: (x.compareTo(y) <op> 0), where <op> is one of the six comparison operators.

## Specified by

compareTo in interface **Comparable<BigDecimal>**

## Declaration

Following is the declaration for **java.math.BigDecimal.compareTo()** method

public int compareTo(BigDecimal val)

## Parameters

**val**- value to which this BigDecimal is to be compared

## Return Value

This method returns -1 if the BigDecimal is less than val, 1 if the BigDecimal is greater than val and 0 if the BigDecimal is equal to val

## Exception

**NA**

## Example

The following example shows the usage of math.BigDecimal.compareTo() method.

package com.tutorialspoint; import java.math.*; public class BigDecimalDemo { public static void main(String[] args) { // create 2 BigDecimal objects BigDecimal bg1, bg2; bg1 = new BigDecimal("10"); bg2 = new BigDecimal("20"); //create int object int res; res = bg1.compareTo(bg2); // compare bg1 with bg2 String str1 = "Both values are equal "; String str2 = "First Value is greater "; String str3 = "Second value is greater"; if( res == 0 ) System.out.println( str1 ); else if( res == 1 ) System.out.println( str2 ); else if( res == -1 ) System.out.println( str3 ); } }

Let us compile and run the above program, this will produce the following result:

Second value is greater
