哪位给看看这个小代码为什么不能运行

[asiazmm]

public class TestArrayCopy{
public static void main(String [] args){
int x[] = new int[]{1,2,3,4,5};
int y[] = new int[]{7,8,9,6,5,4};
System.arraycopy(x,0,y,0,3);
for(int i = 0;i < x.length;i++){
System.out.println(x[i]);
System.out.println();
}
for(int j = 0;j < y.length;j++){}{
System.out.print(y[j]);
System.out.println();
}
}
}

for(int j = 0;j < y.length;j++){}{
System.out.print(y[j]);
System.out.println();
}
写错了，多了一括号，应该为：
for(int j = 0;j < y.length;j++){
System.out.print(y[j]);
System.out.println();
}

[tdy1234]

for(int j = 0;j < y.length;j++){}//这里为什么有2对括号呀大哥
{
System.out.print(y[j]);
System.out.println();
}

public class TestArrayCopy
{
public static void main(String [] args)
{
int x[] = new int[]{1,2,3,4,5};
int y[] = new int[]{7,8,9,6,5,4};

System.arraycopy(x,1,y,0,4);

for(int i = 0;i < x.length;i++)
{
System.out.println(x[i]);
System.out.println();
}

for(int j = 0;j < y.length;j++)
{
System.out.print(y[j]);
System.out.println();
}
}

}

多少给点分吧

public class TestArrayCopy{
private static boolean i;
private static int j;
public static void main(String [] args){
int x[] = new int[]{1,2,3,4,5};
int y[] = new int[]{7,8,9,6,5,4};
System.arraycopy(x,0,y,0,3);
for(int i = 0;i < x.length;i++){
System.out.println(x[i]);
System.out.println();
}
for(int j = 0;j < y.length;j++){}{
System.out.print(y[j]);
System.out.println();
}
}
}
