java - 为什么会发生此错误？ （不兼容的类型：int不能转换为int []）(Why this error is happening? (incompatible types: int cannot be converted to int[]))

Question

When I try to print variable b in this method, I face an error.

(当我尝试使用此方法打印变量b时，遇到错误。)

I didn't initialize the variable b as an array , why this is happening?

(我没有将变量b初始化为array ，为什么会发生这种情况？)

public void print(int[] data){
   int b = 2;
   print(b);
}

This is the error I get : incompatible data type : int cannot be converted to int[]

(这是我得到的错误： 不兼容的数据类型：int无法转换为int [])
