フォームにがJFormattedTextFieldあり、そのフォームを short time: に設定しましたMM/dd/yyyy。

日の部分、または月の部分に 2 つの数字、または年の部分に 4 つの数字を含む日付を入力するとJFormattedTextField 、変更が受け入れられません。

たとえば、次のように入力すると、次の30/11/2013ようになります6/11/15。

しかし、私が入力した場合：6/5/10変更を受け入れます。

誰かがこの問題を解決する方法を教えてくれたら、感謝します。

が与えられた場合、値SimpleDateFormat("MM/dd/yyyy")の寛大な解釈は です。. _ _Calendar30/11/20136/11/2015setLenient(false)JFormattedTextField

この例では、を使用して の有効なエントリInputVerifierをチェックしています。List<SimpleDateFormat>例えば、

static {
    validForms.add(new SimpleDateFormat("MM/dd/yyyy"));
    validForms.add(new SimpleDateFormat("MM/dd/yy"));
    for (SimpleDateFormat f : validForms) {
        f.setLenient(false);
    }
}

補遺：あなたの更新された例では、

SimpleDateFormat f = new java.text.SimpleDateFormat("MM/dd/yyyy");
f.setLenient(false);
jFormattedTextField1.setFormatterFactory(
    new javax.swing.text.DefaultFormatterFactory(
        new javax.swing.text.DateFormatter(f)));
