return StreamofLocalAndMunicipalCompanyEnumvalues filterpredicate 该业务匹配后只获取唯一的匹配数据枚举中名称和值都是唯一不会有相同并匹配多个的情况 findFirst mapmapper orElseGetvalue;vau
The variable "value" should be checked for null before being used in the "orElseGet" method. Here's an updated version of the code that includes the null check:
return Stream.of(LocalAndMunicipalCompanyEnum.values())
.filter(predicate)
.findFirst()
.map(mapper)
.orElseGet(() -> {
if (value != null) {
// Handle the non-null case
return value;
} else {
// Handle the null case
return defaultValue; // Replace defaultValue with your desired default value
}
});
In this updated code, the "orElseGet" method uses a lambda expression that checks if the "value" variable is null. If it is not null, the non-null case is handled and the value is returned. If it is null, the null case is handled and the defaultValue (replace defaultValue with your desired default value) is returned
