Public class dynamicparameters {public static void main (string [] ARGs) {Add (1, 2, 3); add (1, 2, 3);} public static void add (int... ARR) {// supports variable parameters, which are actually an array and automatically built. // note that variable parameters must be the last value of the function. The three vertices and the front and back are free of spaces. // Actually comes from the automatic construction of the main function. Int sum = 0; For (int I: ARR) {sum + = I;} system. Out. println (SUM );}}
