为什么我的代码没有提示输入两次，仅在循环的第二次迭代中？

Question

我正在运行此代码段：

    personalInfo[] pers = new personalInfo[3];
    Scanner input = new Scanner(System.in);

    String inName;
    String inAddress;
    int inAge;
    long inPhoneNumber;

    for(int i=0; i<3; i++){
        pers[i] = new personalInfo();
        System.out.printf("Please input the name for person %d: ", i );
        inName = input.nextLine();
        pers[i].setName(inName);
        System.out.printf("Please input the address for person %d: ", i );
        inAddress = input.nextLine();
        pers[i].setAddress(inAddress);
        System.out.printf("Please input the age for person %d: ", i );
        inAge = input.nextInt();
        pers[i].setAge(inAge);
        System.out.printf("Please input the phone number for person %d, without dashes included (ex. 1112223333): ", i );
        inPhoneNumber = input.nextLong();
        pers[i].setPhoneNumber(inPhoneNumber);
    }

我得到了这个输出：

Please input the name for person 0: name
Please input the address for person 0: address
Please input the age for person 0: 18
Please input the phone number for person 0, without dashes included (ex. 1112223333): 1289308439
Please input the name for person 1: Please input the address for person 1: 

你可以看到，在循环的第一次迭代中，它会提示输入名称，等待输入，然后提示输入地址。但是，在循环的第二次迭代中，它会在同一行上提示输入名称和地址，然后等待输入。这对我来说没有意义。有人可以帮我解释一下吗？
