How can I write an "if" statement for a string variable in Java?
提问by g3n3rallyl0st
This is what I have so far and I have the problem written as a comment on the line I need help with. Any further suggestions would be welcome too. I just need it to end the program when the user enters "stop" as the employee name. Thanks in advance.
这就是我到目前为止所拥有的，并且我将问题写在我需要帮助的行上作为评论。任何进一步的建议也将受到欢迎。当用户输入“停止”作为员工姓名时，我只需要它来结束程序。提前致谢。
package payroll_program_2;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner( System.in );
float hours;
float rate;
String name;
float total_pay;
System.out.println("Please enter employee name");
name = input.next();
if (stop) //THIS IS WHAT I NEED HELP WITH. I DO NOT KNOW HOW TO WRITE
end program //IT CORRECTLY, SO I JUST TYPED WHAT I NEED IT TO DO.
{
}
System.out.println("Please enter hourly rate");
rate = input.nextFloat();
if (rate <0)
{
System.out.printf("Pay rate cannot be negative");
}
System.out.println("Please enter hours worked");
hours = input.nextFloat();
if (hours <0)
{
System.out.printf("Hours cannot be negative");
}
System.out.println("Employee's total pay for this week");
total_pay = hours*rate;
System.out.printf("The total pay for %s is $%.2f\n", name, total_pay);
}

if (name.equals("stop")) {
return;
}
