我想转换java.time.LocalDate成java.util.Date类型.因为我想将日期设置为JDateChooser.或者是否有支持java.time日期的日期选择器？

我需要将十六进制字符串转换为十进制值。我使用了以下方法。但有时它返回错误的十进制值。

十六进制字符串的格式为“00 00 0C 6E”

unsigned long hexToDec(String hexString) {
  unsigned long decValue = 0;
  int nextInt;
  for (long i = 0; i < hexString.length(); i++) {
    nextInt = long(hexString.charAt(i));
    if (nextInt >= 48 && nextInt <= 57) nextInt = map(nextInt, 48, 57, 0, 9);
    if (nextInt >= 65 && nextInt <= 70) nextInt = map(nextInt, 65, 70, 10, 15);
    if (nextInt >= 97 && nextInt <= 102) nextInt = map(nextInt, 97, 102, 10, 15);
    nextInt = constrain(nextInt, 0, 15); …

我需要在数据网格单元格内将 0 和 1 布尔值显示为 YES 和 NO。

<DataGridTextColumn Header="Active" Binding="{Binding stuen.IsDelete}" CanUserResize="False" Width="* "  HeaderStringFormat="" >
    <DataGridTextColumn.ElementStyle>
        <Style TargetType="{x:Type TextBlock}">
            <Setter Property="VerticalAlignment" Value="Center"/>
            <Setter Property="HorizontalAlignment"  Value="Center"/>
        </Style>
    </DataGridTextColumn.ElementStyle>
</DataGridTextColumn>
