导入包要写在类外面
HelloWorld.java:3: error: illegal start of type import java.util.Arrays; ^ HelloWorld.java:3: error: ';' expected import java.util.Arrays; ^ HelloWorld.java:3: error: illegal start of type import java.util.Arrays; ^ HelloWorld.java:3: error: ';' expected import java.util.Arrays; ^ HelloWorld.java:3: error: expected import java.util.Arrays; ^ 5 errors
这是提示的错误
在eclipse里面能成功运行
