String[]？ str2？ =? {? "Like"? "what"? "ba" "two" a。 "Numbers"? "Group" and "Together"? "and"? "for",

"one" and "one" };

int？ strLen 1？ =? str 1 . length； //? Save the length of the first array.

int？ strLen2？ =? str2.length//? Save the length of the second array.

str 1？ =? Arrays.copyOf(str 1，strLen 1？ +? strlen 2)； //? Expand telecom capacity

System.arraycopy(str2，0,? str 1，？ strLen 1，？ strlen 2)； //? Merge the second array with the first array.

system . out . println(arrays . tostring(str 1))； //? Output array

}
