Java.math.BigDecimal.hashCode()方法

java.math.BigDecimal.hashCode() 返回此BigDecimal的雜湊程式碼。兩個BigDecimal物件是數值上相等，但不同的規模（比如2.0和2.00），一般不會有相同的雜湊碼。

宣告

`public int hashCode()`

重寫

• hashCode in class Object

• NA

• NA

例子

```package com.yiibai;

import java.math.*;

public class BigDecimalDemo {

public static void main(String[] args) {

// create 3 BigDecimal objects
BigDecimal bg1, bg2, bg3;

// create 3 int objects
int i1, i2, i3;

bg1 = new BigDecimal("125");
bg2 = new BigDecimal("125.50");
bg3 = new BigDecimal("125.80");

// assign the HashCode value of bg1, bg2, bg3 to i1, i2, i3
// respectively
i1 = bg1.hashCode();
i2 = bg2.hashCode();
i3 = bg3.hashCode();

String str1 = "HashCode of " + bg1 + " is " + i1;
String str2 = "HashCode of " + bg2 + " is " + i2;
String str3 = "HashCode of " + bg3 + " is " + i3;

// print i1, i2, i3 values
System.out.println( str1 );
System.out.println( str2 );
System.out.println( str3 );
}
}```

```HashCode of 125 is 3875
HashCode of 125.50 is 389052
HashCode of 125.80 is 389982```
