How do I print numbers in a different method?

问题

  1. output += String.format("确保数字被打印：\n=> 输出 += String.format("数字 %d 和 %d 是Primetwin", number1, number2);\nnumber1和number2的内容在giveResultPrimeTwin方法中是未知的\n\n建议？", number1, number2);
  1. package ui;
  2. import domein.MyNumbers;
  4. import java.util.Scanner;
  6. public class PrimeTwinApplication {
  7. 	
  8. 	public static void main(String args[]) {
  9. 		int number1, number2;
  10. 		
  11. 		PrimeTwinApplication numbers = new PrimeTwinApplication();
  12. 		number1 = numbers.inputNumber("给一个数字：");
  13. 		number2 = numbers.inputNumber("给一个数字：");
  14. 		
  15. 		MyNumbers mg = new MyNumbers(number1, number2);
  17. 		System.out.printf(numbers.giveResultPrimeTwin(mg));
  18. 	}
  19. 	
  20. 	private int inputNumber(String question) {
  21. 		Scanner input = new Scanner(System.in);
  22. 		int number;
  23. 		System.out.print(question);
  24. 		number = input.nextInt();
  25. 		
  26. 		return number;
  27. 	}
  28. 	
  29. 	private String giveResultPrimeTwin(MyNumbers mg) {
  30. 		String output = "";
  31.        
  32. 		if (mg.isPrimeTwin() == true)
  33. 			output += String.format("数字 %d 和 %d 是Primetwin", mg.getNumber1(), mg.getNumber2());
  34. 		else
  35. 			output += String.format("数字 %d 和 %d 不是Primetwin", mg.getNumber1(), mg.getNumber2());
  37. 	    return output;
  38. 	}
  39. }
英文:

How do I make sure the numbers are printed?
=> output += String.format("The numbers %d and %d are a Primetwin", number1, number2);
the contents of number1 and number2 are not known within the method giveResultPrimeTwin

Suggestions?

  1. package ui;
  2. import domein.MyNumbers;
  4. import java.util.Scanner;
  6. public class PrimeTwinApplication {
  7. 	
  9. 	
  10. 	public static void main (String args[]  )
  11. 	{
  12. 		int number1, number2;
  13. 		
  14. 		PrimeTwinApplication numbers = new  PrimeTwinApplication ();
  15. 		number1 = numbers.inputNumber("Give a number:");
  16. 		number1 = numbers.inputNumber("Give a number:");
  17. 		
  18. 		MyNumbers mg = new MyNumbers (number1, number2);
  20. 		System.out.printf(numbers.giveResultPrimeTwin(mg));
  21. 		
  22. 			}
  23. 	
  24. 	private int inputNumber (String question)
  25. 	{
  26. 		Scanner input = new Scanner (System.in);
  27. 		int number;
  28. 		System.out.print(question);
  29. 		number= input.nextInt();
  30. 		
  31. 		return number;
  32. 	}
  33. 	
  34. 	private String giveResultPrimeTwin(MyNumbers mg)
  35. 	{
  37. 		
  38. 		String output = "";
  39.        
  40. 	
  41. 		if (mg.isPrimeTwin() == true)
  42. 			output += String.format("The numbers %d and %d are a Primetwin", number1, number2);
  44. 		
  45. 		else
  46. 		output += String.format("The numbers %d and %d are not a Primetwin", number1, number2);
  49. 		
  50. 	    return output;
  52. 		
  53. 	}

你需要将number1和number2设置为PrimeTwinApplication类的实例属性。然后你可以在PrimeTwinApplication函数中的任何地方使用它们。

  1. package ui;
  2. import domein.MyNumbers;
  4. import java.util.Scanner;
  6. public class PrimeTwinApplication {
  7.     int number1;
  8.     int number2;
  9.     public static void main(String args[])
  10.     {
  11.         PrimeTwinApplication numbers = new PrimeTwinApplication();
  12.         numbers.number1 = numbers.inputNumber("请输入一个数字:");
  13.         numbers.number2 = numbers.inputNumber("请输入一个数字:");
  14.         
  15.         MyNumbers mg = new MyNumbers(numbers.number1, numbers.number2);
  17.         System.out.printf(numbers.giveResultPrimeTwin(mg)); 
  18.     }
  19.     
  20.     private int inputNumber(String question)
  21.     {
  22.         Scanner input = new Scanner(System.in);
  23.         int number;
  24.         System.out.print(question);
  25.         number= input.nextInt();
  26.         
  27.         return number;
  28.     }
  29.     
  30.     private String giveResultPrimeTwin(MyNumbers mg)
  31.     {
  32.         String output = "";
  33.     
  34.         if (mg.isPrimeTwin() == true)
  35.             output += String.format("数字 %d 和 %d 是孪生质数", number1, number2);
  36.         else
  37.             output += String.format("数字 %d 和 %d 不是孪生质数", number1, number2);
  38.         
  39.         return output;
  40.     }
  41. }
英文:

You need to make number1 and number 2 instance properties of PrimeTwinApplication class. Then you can use it anywhere in PrimeTwinApplication functions.

  1. package ui;
  2. import domein.MyNumbers;
  4. import java.util.Scanner;
  6. public class PrimeTwinApplication {
  7.     int number1;
  8.     int number2;
  9.     public static void main(String args[])
  10.     {
  11.         PrimeTwinApplication numbers = new PrimeTwinApplication();
  12.         numbers.number1 = numbers.inputNumber("Give a number:");
  13.         numbers.number2 = numbers.inputNumber("Give a number:");
  14.         
  15.         MyNumbers mg = new MyNumbers(numbers.number1, numbers.number2);
  17.         System.out.printf(numbers.giveResultPrimeTwin(mg)); 
  18.     }
  19.     
  20.     private int inputNumber(String question)
  21.     {
  22.         Scanner input = new Scanner(System.in);
  23.         int number;
  24.         System.out.print(question);
  25.         number= input.nextInt();
  26.         
  27.         return number;
  28.     }
  29.     
  30.     private String giveResultPrimeTwin(MyNumbers mg)
  31.     {
  32.         String output = "";
  33.     
  34.         if (mg.isPrimeTwin() == true)
  35.             output += String.format("The numbers %d and %d are a Primetwin", number1, number2);
  36.         else
  37.             output += String.format("The numbers %d and %d are not a Primetwin", number1, number2);
  38.         
  39.         return output;
  40.     }
