我是linux中的java编程但它报告了以下错误。有人可以帮我吗?在期待中感谢!
Break.java:4: ';' expected
for (int x:numbers) {

Break.java:11: illegal start of expression
}
^
2 errors
public class Break {
public static void main(String args[]) {
int [] numbers={10,20,30,40,50};
for (int x:numbers){
if (x==30){
break;
}
System.out.print(x);
System.out.print("\n");
}
}
}

您必须使用JDK 1.4或更早版本。您的代码编译为1.5,但不是1.4:
$ javac Break.java
$ javac -source 1.4 -target 1.4 Break.java
Break.java:4: for-each loops are not supported in -source 1.4
(try -source 1.5 to enable for-each loops)
for (int x:numbers){
^
1 error
您必须使用Java 1.5+来使用foreach循环语法which was introduced in Java 1.5。
