如何将字符串转换为枚举和类型？

enum Color {
    Red,
    Green,
    Blue
}

let colorString = "Red";
let colorEnum: Color = Color[colorString as keyof typeof Color];
console.log(colorEnum); // 输出: 0

public enum Color {
    RED,
    GREEN,
    BLUE
}

String colorString = "RED";
Color colorEnum = Color.valueOf(colorString);
System.out.println(colorEnum); // 输出: RED

from enum import Enum

class Color(Enum):
    RED = 1
    GREEN = 2
    BLUE = 3

color_string = "RED"
color_enum = Color[color_string]
print(color_enum) # 输出: Color.RED

enum Color {
    Red,
    Green,
    Blue
}

function stringToEnum(str: string, enumType: any): any {
    return enumType[str as keyof typeof enumType];
}

let colorString = "Red";
let colorEnum = stringToEnum(colorString, Color);
console.log(colorEnum); // 输出: 0

public enum Color {
    RED,
    GREEN,
    BLUE
}

public static <T extends Enum<T>> T stringToEnum(String str, Class<T> enumClass) {
    return Enum.valueOf(enumClass, str);
}

String colorString = "RED";
Color colorEnum = stringToEnum(colorString, Color.class);
System.out.println(colorEnum); // 输出: RED
