java.math.BigInteger.add(BigInteger val) 返回一個BigInteger物件的值是 (this + val).
以下是java.math.BigInteger.add()方法的宣告
public BigInteger add(BigInteger val)
val - 此值被相加到當前的BigInteger
此方法返回BigIntger物件的值, this + val
NA
下面的例子顯示math.BigInteger.add()方法的用法
package com.yiibai; import java.math.*; public class BigIntegerDemo { public static void main(String[] args) { // create 3 BigInteger objects BigInteger bi1, bi2, bi3; // assign values to bi1, bi2 bi1 = new BigInteger("123"); bi2 = new BigInteger("50"); // perform add operation on bi1 using bi2 bi3 = bi1.add(bi2); String str = "Result of addition is " +bi3;; // print bi3 value System.out.println( str ); } }
讓我們編譯和執行上面的程式,這將產生以下結果:
Result of addition is 173
