Simple implementation of large number classes in Java

Large numbers in Java are quite easy to use and very convenient, so they are listed below for ready use

  import java.math.*; 
  import java.util.*; 
 
//基本使用如下： 
            x = in.nextBigInteger(); 
    y = in.nextBigInteger(); 
 
            System.out.println(x.add(y)); //x+y; 
    System.out.println(x.subtract(y)); //x-y; 
    System.out.println(x.multiply(y)); // x*y; 
    System.out.println(x.remainder(y)); // x%y; 
 
            System.out.println(x.abs()); // x的绝对值； 
    System.out.println(x.compareTo(y)==0); //x和y进行比较   
     
    System.out.println(x.toString(2)); // 转化为 x 的 n进制; 
 
            x=BigInteger.ONE; //对x进行赋值 
    x=BigInteger.valueOf(5);// 对x进行赋值，使用的是long/int 类型数据 
 
            System.out.println(x);
