我刚开始学习Java,尝试使用“ Javac”编译以下源代码时,出现以下错误:
“ C:\ Java> javac 99Bottles.java
99Bottles.java:1:错误:预期
公共类99Bottles {//打开类“ 99Bottles”
似乎无法弄清楚这是语法错误还是我遗漏了什么?任何建议将不胜感激,谢谢
public class 99Bottles { //open Class "99Bottles"
public static void main (String[] args) { //Open main method
int Beernum = 99; //delcate intergar called "Beernum" with value of 99
String word = "bottles"; //delcare the string "word" with a value of "bottles"
System.out.println(Beernum + " " + word + "of beer on the walL"); //prints
System.out.println(Beernum + " " + word + "of beer"); //prints
System.out.println("you take one down"); //prints
System.out.println("you pass it around"); //prints
Beernum = Beernum - 1; //subtract 1 from the value of "Beernum"
if (Beernum > 0) { //Check if Beernum is greater than 0
System.out.println(Beernum + " " + "of beer on the wall"); //prints
} else { //if the if statement is not true run this
System.out.println("no more bottles of beer on the wall"); //prints
}
}
}
