java数组中如何去掉最后一个元素并且数组缩小

public class deletelast {
public static void main(String args[]){
char[] arry ={'a','b','c','d','w','6','1'};
   System.out.println(a(arry));
   System.out.println(a(arry).length);
}
static char[] a(char[]arry){

char[]arry1 = new char[arry.length-1];
for(int i = 0;i<arry.length-1;i++){
arry1[i]=arry[i];
}

return arry1;
}
 
}
