java如何将数组里面的数都输出出来

Question

public class a
{
public static void main(String args[])
{
int[] i = {1,2,3,4,5,6,7,8,9};
for(int b=0;b<9;b++)
{
System.out.print(i[b]);
}
}
}

Answer 1

Arrays.toString(a);
System.out.println(Arrays.toString(a));

Answer 2

单词拼写错误，是Arrays,不是Array。只需要 System.out.println(Arrays.toString(a));

Answer 3

是Arrays.toString(a); 不是Array.toString(a);

Answer 4

对的

Answer 5

public class Test {
/**
* @param args
*/
public static void main(String[] args) {

int[] a = { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
for (int i = 0; i < a.length; i++) {
System.out.println(a[i]);
}

}
}
