钱包的java代码中的标识符错误

Question

我收到以下代码的“标识符预期”错误，用于比较2个钱包和打印每对钞票。谢谢你的帮助：

public void printBankNotePairs(Wallet other)
{
    StringBuffer myBuffer = new StringBuffer("Pair: ");

    for(int i = 0; i < count; i++)
    {
        for(int j = 0 + i; j < other.length; j++)
        {
            **if( this.contents[i] == other.[j]){** 
                myBuffer.append(" " + contents[i]) );
                i++;

            }

        }

    }

    System.out.println(myBuffer.toString());

}

Answer 1

似乎您忘记在行

中完成表达式other.[j]

if( this.contents[i] == other.[j]) {

我猜它应该是

other.contents[j]
