两数相乘,结果的长度一定不大于乘数和被乘数的长度之和。 上述也可以用直接用java的BigInteger类实现 publicstaticvoidmain(String[] args) { String a= "98989898989898956898", b = "989892551548781251323265615150"; BigInteger aa=newBigInteger(a); BigInteger bb=newBigInteger(b); System.out.println(aa.multiply(...
二、乘法运算符的使用 在Java中,乘法运算符*使用起来非常简单。下面是一个基本的示例,演示如何使用乘法运算符来计算两个数的乘积。 publicclassMultiplyExample{publicstaticvoidmain(String[]args){inta=5;intb=10;intproduct=a*b;System.out.println("The product of "+a+" and "+b+" is: "+product);}}...
String result = sing_mul[0];for(intz=1; z<len_num2; z++){intlen_res =result.length();//给短的字符串前补充"0".if(sing_mul[z].length()<len_res){//字符串前部进行填充//先反转字符串,补"0",再次反转字符串。StringBuffer sb_z =newStringBuffer(sing_mul[z]); String sb_z_str=sb...
