java - 将公斤转换为磅程序

Question

import javax.swing.JOptionPane;

public class NewClass {


int i = 1;

public static void main(String[] args)
{


    String output = "";                       
    System.out.println("kilograms | pounds");
    System.out.println("--------+-----------");
    for ( i = 1; i <= 199; i ++)
    {            
       // Every table line in between
    System.out.printLn(“| “+i+” | “+i*2.2+” |”);
        }
    System.out.println(output);
    } //end method
} // end class

这里出了什么问题，为什么我不能运行它？尝试显示从 1 到 199 的 KG 列表

Answer 1

你犯了一些错别字。这应该编译:

//Removed import because you aren't using it

public class NewClass {

  public static void main(String[] args)
  {                 
    System.out.println("kilograms | pounds");
    System.out.println("--------+-----------");
    for (int i = 1; i <= 199; i ++) 
    // define i at this point because it's only used in this scope
    {            
      System.out.println("| " + i + " | " + (2.2 * i) + " |");
      // Use normal "
      // you misspelled println
      // put parenthesis around calculations
    }
    System.out.println("");
  } //end method
} // end class

您应该考虑使用像 Eclipse 这样的 IDE 。它突出显示了上述错误。
