I have enum:
public enum Enumz{
FIRST_VALUE(0, "one"),
SECOND_VALUE(1, "two"),
THIRD_VALUE(2, "three")
private int id;
private String name;
}
How can I find enum value if my String value match with enum string name? For example: if I have String = "two" I need to get ENUMZ.SECOND_VALUE.
You can use Java 8 stream alternative to for loop
String serachValue = "two";
Enumz enumz = Arrays.stream(Enumz.values())
.filter(v -> serachValue.equalsIgnoreCase(v.name))
.findFirst().orElse(null);
Good practice is always put it as a static method into the ENUM itself as explained by other @Sagar Gangwal.
public enum Enumz {
FIRST_VALUE(0, "one"),
SECOND_VALUE(1, "two"),
THIRD_VALUE(2, "three");
private int id;
private String name;
Enumz(int id, String name) {
this.id = id;
this.name = name;
}
public static Enumz fromString(String text) {
for (Enumz b : Enumz.values()) {
if (b.name.equalsIgnoreCase(text)) {
return b;
}
}
return null;
}
}
class Sample{
public static void main(String[] args) {
System.out.println(Enumz.fromString("two"));
}
}
You can implement your own method inside enum and call that method every time you want enum using String.
Above code will printing an output as below
OUTPUTSECOND_VALUE
fromString() to EnumSet.allOf(Enumz.class).stream().filter(enumz -> name.equals(enumz.name)).findAny().orElse(null). That you use the EnumSet class and Stream.
