如何在Java中使用三元运算符编写嵌套条件？

Question

Can we write like this using ternary operator? When I wrote like this I am getting error,Please help me.How can I write correct syntax?

(str.charAt(j)==c.charAt(k++)) ? break: k<len1 ? continue:break L1;

Answer 1

Ternary operator is a part of expression and its components must be expressions as well, not the statements . In this case you can easily use if stamement:

if (str.charAt(j)==c.charAt(k++)) 
    break;
else if (k<len1)
    continue;
else 
    break L1;

Or even simpler:

if (str.charAt(j)==c.charAt(k++)) 
    break;
if (k<len1)
    continue;
break L1;

Answer 2

break & continue are always used within a loop; You you might want to recheck your logic.

If you want to write a nested ternary operator the general syntax would be

boolean x=("a".equals("b"))? false: (("b".equals("c"))?true:false);
System.out.println(x);

Output

false
