java.math.BigInteger.hashCode() 返回BigInteger的雜湊程式碼。
以下是java.math.BigInteger.hashCode()方法的宣告
public int hashCode()
Object類的hashCode
NA
此方法返回BigInteger的雜湊程式碼。
NA
下面的例子顯示math.BigInteger.hashCode()方法的用法
package com.yiibai; import java.math.*; public class BigIntegerDemo { public static void main(String[] args) { // create 2 BigInteger objects BigInteger bi1, bi2; // create 2 int objects int i1, i2; // assign values to bi1, bi2 bi1 = new BigInteger("12345"); bi2 = new BigInteger("923456789123"); // assign the hashcode of bi1, bi2 to i1, i2 i1 = bi1.hashCode(); i2 = bi2.hashCode(); String str1 = "HashCode of " +bi1+ " is " +i1; String str2 = "HashCode of " +bi2+ " is " +i2; // print i1, i2 values System.out.println( str1 ); System.out.println( str2 ); } }
讓我們編譯和執行上面的程式,這將產生以下結果:
HashCode of 12345 is 12345 HashCode of 923456789123 is 38827148
