public static void main(String[] args) {
        if (args.length != 2) {
          return;
        }
        String s1 = args[0];
        String s2 = args[1];
        System.out.println("s1: " + s1);
        System.out.println("s2: " + s2);
    
      }

### 1、不带空格的情况 ###

### 2、带空格的情况，需要用双引号将该参数包围 ###

### 3、带空格，同时含双引号 ###

### 处理代码 ###

String param1 = "1 1";
                // 处理参数
                param1 = "\"" + param1.replace("\"","\\\"") + "\"";

示例

public static void main(String[] args) {
            try {
                String param1 = "1 \"1";
                System.out.println(param1);
                param1 = "\"" + param1.replace("\"","\\\"") + "\"";
                String param2 = "2 \"2";
                System.out.println(param2);
                param2 = "\"" + param2.replace("\"","\\\"") + "\"";
                String jarPath = "D:\\xxl.jar";//jar包路径
                String command = "java -jar " + jarPath + " " + param1 + " " + param2;
                Process exec = Runtime.getRuntime().exec(command);
                // printMessage(exec.getInputStream());
                // printMessage(exec.getErrorStream());
                int exit = exec.waitFor();//等待外部命令执行完毕，然后返回执行的结果
                exec.destroy();
                //按照约定，非零状态码表示异常终止。
                if (exit == 0) {
                    System.out.println("正常完成");
                } else {
                    System.out.println("异常结束");
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
