Java“无法解析”到对象数组引用。

Question

我最近一直试图解决涉及对象数组的问题，而我似乎无法解决“对象范围”的问题。

我有以下代码，并在这些行上：

ccaA[n].outputInfo("CCA");

和

clientA[n].outputInfo("Client");

我收到以下错误：

clientA cannot be resolved to a variable

让我困惑，因为它不是10行以上。

熟练的Java程序员可以向我解释一下吗？

public class MakePersonV2 {

    public static void main(String[] args) {

        int n; // Index number 
        int ccaNum, clientNum; // Number of Clients & CCA's to be created

        // introduction
        System.out.println("This main program creates a client and CCA object, "
                + "ensures their data\nfields are assigned values, and finally "
                + "outputs those values.");

        ccaNum = PersonInfoV2.inputQuestion("CCA");
        clientNum = PersonInfoV2.inputQuestion("Client");


        for (n = 0; n <= ccaNum; n++)
        {
            // create a CCA and input CCA's information
            System.out.println("\n\nCreating a CCA and entering information...");
            PersonInfoV2[] ccaA = new PersonInfoV2[n]; // create CCA Object Array
            ccaA[n].inputName();                        // assign a name
            ccaA[n].inputAge();                     // assign an age
            ccaA[n].inputGender();                      // assign a gender
        }

        // create a client and input client's information

        for (n = 0; n <= clientNum; n++)
        {
            System.out.println("\n\nCreating a client and entering information...");
            PersonInfoV2[] clientA = new PersonInfoV2[n];// create Client Object Array
            clientA[n].inputCCAName();                       // assign a name
            clientA[n].inputAge();                      // assign an age
            clientA[n].inputGender();                       // assign a gender

        }



        // output client and CCA information
        for (n = 0; n <= clientNum; n++)
        {
            ccaA[n].outputInfo("CCA");                  // output CCA information
        }

        for (n = 0; n <= clientNum; n++)
        {
            clientA[n].outputInfo("Client");            // output Client information
        }

    } // main

} // end MakePerson
