System.out.println()参数类型必须是对象，而arr[1]的类型是基本类型INT。
应该使用对象包装器将基本类型转换为对象
改成System.out.println(new Integer(arr[1]))再试试

public class Test1 {
  static int arr[] = new int[10];  //otherwise it can't be referenced in the static method main

  public static void main(String args[]) {
    System.out.println(arr[1]);
  }
}
