Java Reflection：如何获取java类的所有getter方法并调用它们

java
import java.lang.reflect.Method;
public class GetterMethodExample {
    private String name;
    private int age;
    private boolean active;
    public GetterMethodExample(String name, int age, boolean active) {

    }
    public int getAge() {

        return active;
    }
    public static void main(String[] args) {
        GetterMethodExample example = new GetterMethodExample("John", 25, true);
        Class clazz = example.getClass();
        Method[] methods = clazz.getDeclaredMethods();
        for (Method method : methods) {
            if (isGetterMethod(method)) {
                try {
                    Object result = method.invoke(example);
                    System.out.println("Method: " + method.getName() + ", Result: " + result);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
    }
    private static boolean isGetterMethod(Method method) {
        String methodName = method.getName();
        Class[] parameterTypes = method.getParameterTypes();
        return methodName.startsWith("get") && parameterTypes.length == 0
                || methodName.startsWith("is") && parameterTypes.length == 0
                && method.getReturnType() == boolean.class;
    }
}

Method: getName, Result: John
Method: getAge, Result: 25
Method: isActive, Result: true
