public class SimpleProgram {
    public static void main(String[] args){
        System.out.println("A proverb");
        String Proverb  = "Practice makes perfect!";
        System.out.println("Proverb");

Answer 3

您发布的程序将不编译。这是以下版本：

 

public class SimpleProgram {

    public static void main( String[] args ) {

      System.out.println( "A proverb:" );
      String proverb  = "Practice makes perfect!";
      System.out.println( "Proverb" );
      int characterCount = proverb.length();
      System.out.println( "The Proverb has " + characterCount + " Characters" );
    }
}

您可以编译它并运行：

 

$ javac SimpleProgram.java 
$ java SimpleProgram
A proverb:
Proverb
The Proverb has 23 Characters

Answer 4

编译do java SimpleProgram

如果你不想这样做来回Textpad！
