String 단어 한개씩 쪼개기

1. 1차배열 / toCharArray

package day0122;
import java.util.Arrays;
public class Solution {

    public static void main(String[] args) {
        String str = "abcdefg";
        char[] arr = new char[5];
        arr = str.toCharArray();
        System.out.println(Arrays.toString(arr)+"");

        //2차배열 / toCharArray
        char[][] arr1 = new char[5][];
        arr1[0] = str.toCharArray();
        System.out.println(Arrays.toString(arr1[0])+"");

        //string[]
        String[] test = new String[100];
        test = str.split("");
        System.out.println(Arrays.toString(test));



    }
}

2. 2차배열 / toCharArray

package day0122;
import java.util.Arrays;
public class Solution {

    public static void main(String[] args) {
        String str = "abcdefg";

        //2차배열 / toCharArray
        char[][] arr1 = new char[5][];
        arr1[0] = str.toCharArray();
        System.out.println(Arrays.toString(arr1[0])+"");
    }
}

3. String 배열

package day0122;
import java.util.Arrays;
public class Solution {

    public static void main(String[] args) {
        //string[]
        String[] test = new String[100];
        test = str.split("");
        System.out.println(Arrays.toString(test));



    }
