BigInteger valueOf方法找不到符号

Question

我创建了一个由BigInteger对象组成的数组。当我想将数字赋给数组时，我得到一个找不到符号的错误。你可以帮我吗？这是代码：

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是一个静态方法

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