如何仅在键入所有输入后才打印输出，而不是逐行打印？

Question

我有一名员工class:

public class Employee{
  private String firstName;
  private String lastName;
  private double salary;
  private double rate;

  public Employee(String firstName, String lastName, double salary){
    this.firstName = firstName;
    this.lastName = lastName;
    this.salary = salary;
  }

  public String getFirstName(){
    return firstName;
  }

  public String getLastName(){
    return lastName;
  }

  public double getSalary(){
    return salary/1000;
  }

  public double setSalaryIncrease(double rate){
    if ((rate-1)*100>=0){
      this.rate = ((rate-1)*100);
      return this.rate;
    }
    else{
      this.rate = -((rate-1)*100);
      return this.rate;
    }
  }

  public String toString(){
    return firstName+" "+lastName+": salary is "+String.format("%.0f", salary/1000)+"K, annual raise is "+String.format("%.0f", rate)+"%";
  }
}

在我的主要 class、

public class Main {
  public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);

    while (sc.hasNext()) {
      Employee employee = new Employee(sc.next(), sc.next(), sc.nextDouble());
      employee.setSalaryIncrease(sc.nextDouble());
      System.out.println(employee);
    }
  }
}

例如，如果我有一个输入列表，例如

Mohammad Ali 24000.0 1.11
Steve Gates 36000.0 1.05
Michael Jordan 71000.0 1.07

我希望仅在扫描完所有 3 个输入后才打印它。但是，我最终在扫描每一行后打印每一行，即

穆罕默德·阿里 24000.0 1.11

Mohammad Ali：工资24K，年涨幅11%
史蒂夫·盖茨 36000.0 1.05

Steve Gates：工资36K，年涨幅5%

如何修改我的 toString() 方法以在读取所有输入后将所有内容作为一个整体打印出来，而不更改我的主要 class？

Answer 1

System.out.println(); prints every string in new line

尝试System.out.print("string") 在 while 循环之后你可以使用 System.out.println("") 跳转到新行

如何仅在键入所有输入后才打印输出，而不是逐行打印？

How do I print the output only after keying in all the inputs, instead of having it printed line by line?
