Example of Java's method to simplify programming using annotations and reflections

This article describes the method of simplifying programming using annotations and reflections in Java. Share it for your reference, as follows:

A finishing touch

When a large number of methods are called, reflection and annotation can be used to simplify programming.

Two code

@interface testAnnoation10 {
  public String name() default "methodname";
  public String unit() default "unit";
}
public class ch11_10 {
  public static void main( String[] args ) throws Exception {
    ch11_10 ch9 = new ch11_10();
    Method method[] = ().getMethods();
    for (Method method2 : method) {
      Annotation annotation = ();
      Class<?> ts[] = ();
      if (().indexOf("getData") == -1) continue;
      ArrayList<Object> params = new ArrayList<Object>();
      for (Class<?> class1 : ts) {
        if (().equals("int")) {
          (10);
        }
        if (().equals("String")) {
          ("100");
        }
      }
      if (annotation != null) {
        testAnnoation10 t9 = (testAnnoation10) annotation;
        (() + " is " + (ch9, ()) + " " + ());
      }
    }
  }
  @testAnnoation10(name = "SOC", unit = "%")
  public int getData1( int a ) {
    return a;
  }
  @testAnnoation10(name = "Electricity", unit = "Ah")
  public String getData2( String b ) {
    return b;
  }
  @testAnnoation10(name = "Tempreture", unit = "AF")
  public int getData3( int a, int b ) {
    return a + b;
  }
}

Three Run

Tempreture is 20 AF
Electricity is 100 Ah
SOC is 10 %
