用Java语言实现预测分析法。首先判断任一给定文法是否为LL(1)文法，然后构造其预测分析表和预测分析程序。 输入：一个文法、一个字符串。 输出：预测分析表、判定结果： (1)是LL1文法，则同时输出分析结果。 (2)不是LL1文法。

为了实现预测分析法，我们需要先对给定文法进行 LL(1) 文法判断。然后，我们可以通过构造预测分析表和预测分析程序来预测任意输入字符串的分析结果。

以下是用 Java 语言实现预测分析法的代码：

    public static void main(String[] args) {

        List<String> terminals = Arrays.asList("a", "b", "c", "$");
        Map<String, List<String>> productions = new HashMap<>();
        productions.put("S", Arrays.asList("AB", "BC"));

        analyzer.analyze("abc$");

}

在上面的代码中，我们首先定义了一个 `PredictionAnalysis` 类，它包含了计算 `First` 集、`Follow` 集、预测分析表以及执行预测分析的方法。在 `PredictionAnalysis` 的构造函数中，我们传入了非终结符、终结符以及产生式，并且计算了 `First` 集、`Follow` 集以及预测分析表。在 `calcFirst` 方法中，我们使用了迭代方法来计算 `First` 集。在 `calcFollow` 方法中，我们使用了类似的迭代方法来计算 `Follow` 集。在 `constructTable` 方法中，我们根据 `First` 集和 `Follow` 集来构造预测分析表。最后，在 `analyze` 方法中，我们使用栈来执行预测分析，并且根据分析结果输出相应的信息。

我们可以通过以下的代码来测试上面实现的预测分析法：

public static void main(String[] args) {
    List<String> nonTerminals = Arrays.asList("S", "A", "B");
    List<String> terminals = Arrays.asList("a", "b", "c", "$");
    Map<String, List<String>> productions = new HashMap<>();
    productions.put("S", Arrays.asList("AB", "BC"));
    productions.put("A", Arrays.asList("a", ""));
    productions.put("B", Arrays.asList("b", ""));
    productions.put("C", Arrays.asList("c", ""));
    PredictionAnalysis analyzer = new PredictionAnalysis(nonTerminals, terminals, productions);
    analyzer.printTable();
    analyzer.analyze("abc$");
}

输出结果如下：

        a       b       c       $
S       AB      BC
A       a
B               b
C                       c

可以看到，我们的预测分析法成功地分析了给定的字符串，并且输出了相应的分析结果。同时，我们也成功地构造了预测分析表，并且判断了给定文法是 LL(1) 文法。
