Array数组声明初始化的一些写法

public class Array {
public static void main(String[] args) {

String  array_1[]=new String[]{"ew","fe"};

String[]  array_2=new String[]{"ew","fe"};

String  []array_3=new String[]{"ew","fe"};

String  array_4[]={"ew","fe"};

// String  array_5[];
// array_5={"ew","fe"};//这是不行的会报错

String  array_6[];
array_6=new String[]{"ew","fe"};//这样没有问题

System.out.println(array_1[1]);
System.out.println(array_2[1]);
System.out.println(array_3[1]);
System.out.println(array_4[1]);
System.out.println(array_6[1]);
}

}
