在J2ME中从电话簿加载联系人

Question

我在下面实施了此代码，以便从手机的地址簿中读取联系人

问题是，如果电话簿中的所有号码都保存在SIM卡中，它会读取并显示联系人以供选择。
但是如果手机内存中包含任何数字，则会出现应用程序错误。(OutOfMemoryException) 我该怎么办（PS不介意那里的一些System.out.println语句。我用它们进行调试）

public void execute() {
        try {

            if (allContactLists.length != 0) {
                for (int i = 0; i < allContactLists.length; i++) {
                    System.out.println(allContactLists[i] + " " + allContactLists[1]);
                    System.out.println(allContactLists.length);
                    loadNames(allContactLists[i]);
                    System.out.println("Execute() error");
                }
