+
+## 1. 반복문
+이중 for문을 사용하여 값을 출력 한다.
+
+* 예제
+
+```java
+public class Test {
+    public static void main(String[] args) {
+        int[][] ary = {{1, 2}, {3, 4, 5}, {6, 7, 8, 9}};
+        for (int[] ar : ary) {
+            for (int val : ar) {
+                System.out.println(val);
+            }
+        }
+    }
+}
+```
+
+* 결과
+
+```text
+1
+2
+3
+4
+5
+6
+7
+8
+9
+```
+
+## 2. Arrays.deepToString()
+`java.util.Arrays.deepToString()` 메소드를 사용하여 2차원 배열 값을 문자열로 출력 한다.
+
+* 예제
+
+```java
+import java.util.Arrays;
+
+public class Test {
+    public static void main(String[] args) {
+        int[][] ary = {{1, 2}, {3, 4, 5}, {6, 7, 8, 9}};
+        System.out.println(Arrays.deepToString(ary));
+    }
+}
+```
+
+* 결과
+
+```text
+[[1, 2], [3, 4, 5], [6, 7, 8, 9]]
+```
