# BigDecimal hashCode() Method in Java

The java.math.BigDecimal.hashCode() returns the hash code for this BigDecimal. The hashcode will generally not be the same for two BigDecimal objects with equal values and different scale (like 4743.0 and 4743.00).

Syntax:

`public int hashCode()`

Parameters: This method does not accept any parameters.

Return Values: This method returns an integer value which is equal to the hashCode Value of the BigDecimal Object.

Examples:

```Input : BigDecimal = 67891
Output : Hashcode : 2104621

Input : BigDecimal = 67891.000
Output : Hashcode : 2104621003
```

Below programs illustrate the hashCode() function of BigDecimal class:
Program 1:

 `// Java program to demonstrate hashCode() method ` `import` `java.io.*; ` `import` `java.math.*; ` ` `  `public` `class` `GFG { ` ` `  `    ``public` `static` `void` `main(String[] args) ` `    ``{ ` `        ``// Creating a BigDecimal object ` `        ``BigDecimal b; ` ` `  `        ``// Assigning value ` `        ``b = ``new` `BigDecimal(``4743``); ` `        ``System.out.print(``"HashCode for "` `+ b + ``" is "``); ` `        ``System.out.println(b.hashCode()); ` `    ``} ` `} `

Output:

```HashCode for 4743 is 147033
```

Program 2: This program will illustrate that hashcode for two different BigDecimals with equal value but different scale will be different.

 `// Java program to demonstrate hashCode() method ` `import` `java.io.*; ` `import` `java.math.*; ` ` `  `public` `class` `GFG { ` ` `  `    ``public` `static` `void` `main(String[] args) ` `    ``{ ` `        ``// Creating 2 BigDecimal objects ` `        ``BigDecimal b1, b2; ` ` `  `        ``// Assigning values ` `        ``b1 = ``new` `BigDecimal(``"4743"``); ` `        ``b2 = ``new` `BigDecimal(``"4743.000"``); ` ` `  `        ``int` `i1, i2; ` ` `  `        ``i1 = b1.hashCode(); ` `        ``i2 = b2.hashCode(); ` ` `  `        ``if` `(i1 == i2) { ` `            ``System.out.println(``"HashCodes of "` `+  ` `            ``b1 + ``" and "` `+ b2 + ``" are equal."``); ` `            ``System.out.println(``"Both their HashCodes are "` `+ ` `            ``i1 + ``"."``); ` `        ``} ` `        ``else` `{ ` `            ``System.out.println(``"HashCodes of "` `+ b1 + ``" and "`  `            ``+ b2 + ``" are not equal."``); ` `            ``System.out.println(``"HashCodes of "` `+ b1 + ``" is "`  `            ``+ i1 + ``" and "` `+ b2 + ``" is "` `+ i2 + ``"."``); ` `        ``} ` `    ``} ` `} `

Output:

```HashCodes of 4743 and 4743.000 are not equal.
HashCodes of 4743 is 147033 and 4743.000 is 147033003.
