You can use the ReflectionAPI to achieve this. Just get all methods from your class you wish to invoke and compare theire names with your string.

here is an example:

public class HelloWorld { public static void main(String[] args) { HelloWorld hello = new HelloWorld(); String[] calls = { "def", "abc", "ghi" }; try { Method[] methods = HelloWorld.class.getMethods(); for (String string : calls) { for (Method method : methods) {  if (method.getName().equalsIgnoreCase(string)) {   method.invoke(hello, null); } } } } catch (Exception e) { // TODO: handle exception } } public void abc() { System.out.println("abc"); } public void def() { System.out.println("def"); } public void ghi() { System.out.println("ghi"); } 

}

BUT it's a bad design and you should rethink your application flow!

You can use the ReflectionAPI to achieve this. Just get the method with this name from your desired class (if available ) and invoke it with your args, in this case null.

BUT it's a bad design and you should rethink your application flow!

here is an example:

public class HelloWorld { public static void main(String[] args) { HelloWorld hello = new HelloWorld(); String[] calls = { "def", "abc", "ghi" }; try { for (String call : calls) { Method method = HelloWorld.class.getMethod(call, null); method.invoke(hello, null); } } catch (Exception e) { // TODO: handle exception } } public void abc() { System.out.println("abc"); } public void def() { System.out.println("def"); } public void ghi() { System.out.println("ghi"); }
