how to declare jagged array in java code example
Example 1: jagged array java
int[][] numbers = new int[7][];
// row 0 gets 5 columns
numbers[0] = new int[5];
// row 1 gets 11 columns
numbers[1] = new int[11];
// etc...
Example 2: how to get the length of a jagged array java
public static void main(String[] args) {
int[][] foo = new int[][] {
new int[] { 1, 2, 3 },
new int[] { 1, 2, 3, 4},
};
System.out.println(foo.length); //2
System.out.println(foo[0].length); //3
System.out.println(foo[1].length); //4
}
