MethodgetMethod(Object instance, String methodName, Class[] parameters)
get Method 
return getMethod(instance.getClass(), methodName, parameters);
MethodgetMethod(Object o, String methodName)
get Method 
if ((methodName == null) || (o == null)) {
    return null;
Method[] ms = o.getClass().getMethods();
for (int i = 0; i < ms.length; i++) {
    Method m = ms[i];
    if (m.getName().equals(methodName)) {
        return m;
...
MethodgetMethod(Object o, String methodName, Class[] args)
get Method 
return getMethod(o.getClass(), methodName, args);
MethodgetMethod(Object o, String methodName, Class[] paramTypes)
get Method 
Class clz = o.getClass();
return clz.getMethod(methodName, paramTypes);
MethodgetMethod(Object obj, Class[] paramTypes, String methodName)
Get the method given in string in input corresponding to the given arguments. 
Method method = obj.getClass().getMethod(methodName, paramTypes);
return method;
MethodgetMethod(Object obj, String fieldName)
Get a field in an object. 
try {
    Method method = obj.getClass().getMethod("get" + fieldName);
    return method;
} catch (Exception t) {
    return null;
MethodgetMethod(Object obj, String methodName)

Method[] ms = obj.getClass().getMethods();
for (Method m : ms) {
    if (m.getName().equals(methodName)) {
        return m;
if (methodName.contains("_")) {
    String[] nameSet = methodName.split("_");
...
MethodgetMethod(Object obj, String methodName, Class paramClass)
get Method 
return getMethod(obj, methodName, new Class[] { paramClass });
MethodgetMethod(Object obj, String methodName, Class... parameterTypes)
get Method 
try {
    Method method = getClass(obj).getDeclaredMethod(methodName, parameterTypes);
    method.setAccessible(true);
