Java的：＆QUOT;匿名＆QUOT;数组中的for-each循环 [英] Java: "Anonymous" array in for-each-loop

问题描述

当我试图在一些特殊的for循环我认为Java的似乎不喜欢把一个匿名数组权为源动力的一个的for-each循环：

While I was trying something special in for loop I recognized that Java doesn't seem to like putting an anonymous array right as the source for a for-each-loop:

for (String crt : {"a","b","c"} ) {
    doSomething();
}

其实没有，而

String[] arr = {"a","b","c"};
for (String crt : arr ) {
    doSomething();
}

确实

即使铸造数组的String []于事无补。当将光标移到第一个版本，日食告诉我：

Even casting the array to String[] doesn't help. When moving the cursor over the first version, eclipse tells me:

类型不匹配：不能从String转换[]为String 而意为CRT

这是一个错误吗？

推荐答案

这将工作：

for (String crt : new String[]{"a","b","c"} ) {
    doSomething();
}
