System.out.println("To get started please enter a temperature");
temp = keyboard2.nextDouble();
System.out.println("Did you submit Farenheight or Celsius?");
System.out.println("Type f for farenheight or c for celsius: ");
tempScale = keyboard1.nextLine();
if (tempScale.equals("f") || tempScale.equals("F")){
System.out.println("you entered in " + temp + " degrees farenheight.");

convertTemp();

因此,我是一所大学的学生,并且我正试图找出这份家庭作业,但尚未找到答案。无论我尝试什么,我都会不断收到有关方法调用的错误,任何人都可以帮助我确定如何成功地将方法调用为主方法。真的需要帮助吗?
但我不断收到此错误:
TemperatureConverter.java:62:错误:类中的方法convertTemp
TemperatureConverter不能应用于给定类型;
convertTemp();
^
必需:String,String,double,double
找到:没有参数
原因:实际和正式论点清单的长度不同
1个错误
---- jGRASP楔2:进程的退出代码为1。
---- jGRASP:操作完成。
最佳答案
您的函数定义说它需要4个参数:
public static void convertTemp(
String tempScale,
String Answer,
double temp,
double result)
但是当您调用它时,您传递了0个参数:
convertTemp();
