Java 类型转换工具类，持续更新

简介

将项目中用到的类型转换做个记录。

详细代码

 @Component
 public class TypeUtil {
  // [start]字符串转各种格式
 
  // 字符串转日期(格式:"yyyyMMdd")
  public static Date StrToDateFirst(String str) {
   DateFormat format = new SimpleDateFormat("yyyyMMdd");
   Date date = null;
   try {
    date = format.parse(str);
   } catch (ParseException e) {
    e.printStackTrace();
   }
   return date;
  }
 
  // 字符串转日期(格式:"dd/MM/yyyy")

   try {
    date = format.parse(str);
   } catch (ParseException e) {
    e.printStackTrace();

   } catch (Exception e) {
    e.printStackTrace();
   }
   return integer;

  // 字符串转Double
  public static Double StrToDouble(String str) {

   try {
    double1 = Double.parseDouble(str);
   } catch (Exception e) {
    e.printStackTrace();
   }

   } catch (Exception e) {
    e.printStackTrace();

  // [end]
