The list of methods to do Reflection Method Setter Get are organized into topic(s).

Method

StringgetSetterName(Field field)
get Setter Name 
String name = field.getName();
return "set" + name.substring(0, 1).toUpperCase(Locale.US) + name.substring(1);
StringgetSetterName(final Field field)
get Setter Name 
return "set" + capitalizeFieldName(field);
StringgetSetterName(Method m)
get Setter Name 
String name = m.getName();
if (name.substring(0, 3).equals("set"))
    name = name.substring(3);
return name;
StringgetSetterName(Method m)
Get setter name. 
String name = m.getName();
if (name.startsWith("set") && (name.length() >= 4) && m.getReturnType().equals(void.class)
        && (m.getParameterTypes().length == 1)) {
    return Character.toLowerCase(name.charAt(3)) + name.substring(4);
return null;
StringgetSetterName(Method method)
get Setter Name 
String name = getDefaultPropertyName(method);
if (name == null)
    return null;
return "set" + name;
StringgetSetterName(String name)
get Setter Name 
return "set" + capitalizeFirstLetter(name);
MethodgetSetterOrGetter(Class clazz, String name, boolean isSetter)
get Setter Or Getter 
String exceptMethodName = getSetterOrGetterName(name, isSetter);
Method[] methods = clazz.getMethods();
if (methods != null) {
    for (Method method : methods) {
        if (method.getName().equals(exceptMethodName) && !Modifier.isAbstract(method.getModifiers())
                && Modifier.isPublic(method.getModifiers())) {
            return method;
return null;
MapgetSetters(Class clazz)
Returns a Map of setter methods of the given class.

The key of the map contains the name of the attribute that can be accessed by the setter, the value the setter itself (an instance of java.lang.reflect.Method). 

final Map<String, Method> accessors = new HashMap<String, Method>();
final Method[] methods = clazz.getMethods();
for (Method method : methods) {
    String name;
    String methodName;
    methodName = method.getName();
    if (!methodName.startsWith("set")) {
        continue;
...
Method[]getSetters(Class clazz)
get Setters 
List<Method> outM = new ArrayList<Method>();
for (Method m : clazz.getMethods()) {
    if (m.getParameterTypes().length == 1 && m.getName().startsWith("set") && m.getReturnType() == null) {
        outM.add(m);
return outM.toArray(new Method[outM.size()]);
ListgetSetters(Class klass)
get Setters 
List<Method> res = new ArrayList<>();
Method[] methods = klass.getDeclaredMethods();
for (Method mth : methods) {
    int mod = mth.getModifiers();
    if (Modifier.isPublic(mod) && !Modifier.isStatic(mod) && mth.getParameterCount() == 1
            && mth.getName().matches("^set.*") && !isDeprecated(mth)) {
        res.add(mth);
res.sort((o1, o2) -> {
    int cmp = o1.getName().compareToIgnoreCase(o2.getName());
    return cmp;
});
return res;
