Description

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

Method

StringgetMethodName(String prefix, String fieldName)
get Method Name 
return prefix + fieldName.substring(0, 1).toUpperCase() + fieldName.substring(1);
StringgetMethodNameAndDescriptor(Method m)
Returns a string consisting of the given method's name followed by its "method descriptor", as appropriate for use in the computation of the "method hash". 
StringBuffer desc = new StringBuffer(m.getName());
desc.append('(');
Class[] paramTypes = m.getParameterTypes();
for (int i = 0; i < paramTypes.length; i++) {
    desc.append(getTypeDescriptor(paramTypes[i]));
desc.append(')');
Class returnType = m.getReturnType();
...
HashMapgetMethodNameList(Class theClass)
getMethodNameList 
HashMap<String, Integer> methodsAndParams = new HashMap<String, Integer>();
String className = theClass.getCanonicalName();
Method[] classMethods = theClass.getDeclaredMethods();
String currMethodCanonicalName = "";
String currMethodName = "";
int currMethodNumberParams = 0;
for (int i = 0; i < classMethods.length; i++) {
    currMethodCanonicalName = classMethods[i].toString();
...
StringgetMethodNameMinusGet(Method aMethod)
get Method Name Minus Get 
String result = aMethod.getName();
if (result.startsWith(fGET)) {
    result = result.substring(fGET.length());
return result;
VectorgetMethodNames(Class cls, boolean insertDefaultValues)
Returns a Vector of String s that are the full Method names, with parameters for the given class. 
Method[] methodsArray = cls.getMethods();
Vector methods = new Vector(methodsArray.length);
for (int i = 0; i < methodsArray.length; i++) {
    String term = getMethodName(methodsArray[i], insertDefaultValues);
    methods.add(term);
return methods;
String[]getMethodNames(Class cls)
Gets all methodnames from the given class as an String array. 
Method[] methods = cls.getDeclaredMethods();
String[] methodNames = new String[methods.length];
for (int i = 0; i < methods.length; i++) {
    methodNames[i] = methods[i].getName();
return methodNames;
StringgetMethodNameWithClassName(Method a_Method)
Return method name from Method object 
if (a_Method == null) {
    throw new NullPointerException("Parameter method is null");
StringBuffer l_StringBuffer = new StringBuffer();
l_StringBuffer.append(a_Method.getReturnType().getName());
l_StringBuffer.append(" ");
l_StringBuffer.append(a_Method.getDeclaringClass().getName());
l_StringBuffer.append(".");
...
MethodgetMethodOnlyByName(Class c, String methodName)
Searches in the given class for the given method name. 
Method method = null;
for (Method m : c.getMethods()) {
    if (m.getName().equals(methodName)) {
        method = m;
        break;
if (method == null) {
...
MethodgetMethodOrNull(Class cls, String name, Class[] args)
Get a method using reflections. 
try {
    return cls.getMethod(name, args);
} catch (NoSuchMethodException nsme) {
    return null;
StringgetMethodPropertyName(java.lang.reflect.Method method)
get Method Property Name 
final String methodName = method.getName();
if (methodName.startsWith("get") && methodName.length() > 3) {
    return uncapitalize(methodName.substring(3, methodName.length()));
} else {
    throw new RuntimeException("Incorrect getter name: " + methodName);
