在 Java 中为枚举分配自定义值

package delftstack;

enum Programming_Usage {
  // enum constructor calling with one custom string value
  PYTHON("DataScience"),
  PHP("WebDevelopment"),
  JAVA("AndroidDevelopment"),
  MATLAB("ImageProcessing");

  // declare the private string to get values later
  private String usage;

  // get usage of programming language method
  public String get_usage() {
    return this.usage;
  }

  // enum constructor
  private Programming_Usage(String usage) {
    this.usage = usage;
  }
}

public class Enum_Value {
  public static void main(String args[]) {
    // This example will print usage with corresponding programming language.
    Programming_Usage[] usages = Programming_Usage.values();

    for (Programming_Usage usage : usages) {
      // use get usage method method to get the values of usage and programming language
      System.out.println(
          "For " + usage.get_usage() + ", we mostly use " + usage.name() + " programming");
    }
  }
}

For DataScience, we mostly use PYTHON programming
For WebDevelopment, we mostly use PHP programming
For AndroidDevelopment, we mostly use JAVA programming
For ImageProcessing, we mostly use MATLAB programming
