RxJava 数学运算符 示例

package com.yiidian;

import io.reactivex.Observable;

public class ObservableTester  {
   public static void main(String[] args)  throws InterruptedException {    
      Integer[] numbers = { 1, 2, 3, 4, 5, 6};
      String[] letters = {"a", "b", "c", "d", "e", "f", "g"};
      final StringBuilder result = new StringBuilder();
      Observable<String> observable1 = Observable.fromArray(letters);
      Observable<Integer> observable2 = Observable.fromArray(numbers);
      Observable.concat(observable1, observable2)
         .subscribe( letter -> result.append(letter));
      System.out.println(result);
   }
}

输出结果为：
