BigInteger valueOf 方法找不到符号

Question

我创建了一个包含 BigInteger 对象的数组。当我想将数字分配给数组时，出现找不到符号错误。你能帮助我吗？那是代码：

import java.io.*;
import java.util.*;
import java.math.BigInteger;

public class Solution
{
    public static void main(String[] args) 
    {
        Scanner in = new Scanner(System.in);
        int t1= in.nextInt();
        int t2= in.nextInt();
        int n= in.nextInt();

        BigInteger[] arr = new BigInteger[n];
        arr[0] = new BigInteger.valueOf(t1);
        arr[1] = new BigInteger.valueOf(t2);

    }
}

输入值为 0 1 5。 这是错误：

Solution.java:15: error: cannot find symbol
        arr[0] = new BigInteger.valueOf(t1);
                               ^
  symbol:   class valueOf
  location: class BigInteger
Solution.java:16: error: cannot find symbol
        arr[1] = new BigInteger.valueOf(t2);
                               ^
  symbol:   class valueOf
  location: class BigInteger
2 errors

Answer 1

valueOf是静态方法

arr[0] = BigInteger.valueOf(t1);
