java - 错误：没有'if'的'else'..有什么问题？

Question

这是我的代码，我仍然不知道我的问题是什么

if ((int) ch[j]== (int) ch2)
{ for ( k=j; k<=j ; k++){
System.out.print(ch[j]+" ");
}

else 
System.out.print("Sorry we didn't find it");

Answer 1

你错过了关闭}你的if

if ((int) ch[j]== (int) ch2){ 
  for ( k=j; k<=j ; k++){
       System.out.print(ch[j]+" ");
    } //for loop closing
} //here (missing for if)
else 
    System.out.print("Sorry we didn't find it");

使用适当的缩进，这将帮助您找到这些错误。

Answer 2

你错过了一个}。

应该

if ((int) ch[j]== (int) ch2)
{ for ( k=j; k<=j ; k++){
System.out.print(ch[j]+" ");
}
}
else 
System.out.print("Sorry we didn't find it");

Answer 3

if ( (int) ch[j] == (int) ch2)
{ 
   for ( k=j; k<=j ; k++)
   {
      System.out.print(ch[j]+" ");
   }
**}**
else 
   System.out.print("Sorry we didn't find it");
