向各位路过的大神求问
我自己在写这段程序的时候IDE报错,但不知道自己怎么改,求大神帮助
Java code

public class Insert<E> {
    protected E value;
    protected int position;
    protected Object[] arr;
    
    public Insert (E value, int position, Object[] arr){
        this.value=value;
        this.position=position;
        this.arr=arr;
        if(position<0 ||position>=arr.length)
            throw new IndexOutOfBoundsException();
        else if(position==arr.length-1)
            this.insert();
        else{
            this.resize();
            this.replace();
            this.insert();
        }
    }
    
    private void insert()
    {
        arr[position]=value;
    }
    
    private void resize()//resize the given array with a new length.
    {
        int newLength=arr.length+1;
        Object[] temp=new Object[newLength];
        System.arraycopy(temp, 0, arr, 0, arr.length);
        arr=temp;
    }
    
    private void replace()
    {
        for(int i=arr.length-2;i>position;i--)
        {
            arr[i+1]=arr[i];
        }
    }


下面是main
Java code

public class MainPanel {
    public static void main(String[] args)
    {
        char[] arr1={'a','b','c','d','f','g','h','i','j'};
        Insert<Character> ins=new Insert<Character>('Z',2,arr1);
    }


其中这段报错Insert<Character> ins=new Insert<Character>('Z',2,arr1);
我不知道问题在哪里。我刚学JAVA不久,很多都还不懂,问题虽愚蠢,但求路过的大神赐教。


------解决方案--------------------
测试了下:
应该把数组char[] arr1 设置为Object类型。

Java code

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Object[] arr1={'a','b','c','d','f','g','h','i','j'};
        Insert<Character> ins=new Insert<Character>('Z',2,arr1);
   
    }
