To get an enum value from a string value in Java, you can use the valueOf method of the enum type. Here's an example of how you might do this: public enum Color { RED, GREEN, BLUE } // ... String colorString = "RED"; Color color = Color.valueOf(colorString); This will ...
首先,我们创建一个名为"Color"的Java Enum类,其中包含一些颜色常量。 publicenumColor{RED,GREEN,BLUE} 1. 2. 3. 4. 5. 步骤2:编写一个方法来获取Enum值 接下来,我们编写一个方法来获取Enum值,该方法接受一个Color枚举作为参数,并返回对应的值。 publicclassEnumUtil{publicstaticStringgetValue(Colorcolor){s...

String cellValue= "";if(cell ==null) {returncellValue; } CellType cellType=cell.getCellTypeEnum();//把数字当成String来读,避免出现1读成1.0的情况if(cellType ==CellType.NUMERIC) { cell.setCellType(CellType.STRING); }//判断数据的类型switch(cellType) {caseNUMERIC://数字、日期if(DateUtil...
java 获取未知枚举的集合(get unknown enum list) 两个方法都可以将一个未知的枚举中所有成量读取出来 如果系统中有好几个ORM实体使用枚举作为成员变量,在页面中又需要将这些枚举表现为select标签,就可以使用这个方法了。 public<EextendsEnum<E>>Map<Integer, String>getMap(Class<E>enumType){...
