It will call (1) because the method resolution algorithm gives priority to methods that do not use varargs. To force it to use (2) you can pass an array or cast the first parameter to Object: myMethod(new Object[] { “name”, new MyClass() }); //or myMethod((Object) “name”, new MyClass()); 1 solved Method Overloading – Java
Read a line: Read String line by line in Java Split each line using a space character: Java split string to array The result of #2 will give you an array of String Objects. Use the HashMap data structure (stores a key/value pair) to store each element: HashMap hashMap = new HashMap(); hashMap.put(key, value); ie. … Read more
