Write Java codes to print all of the values from the array.

Answer 1

//TestCode.java
public class TestCode {
    public static void main(String[] args) {
        String [][]cities = {{"New York", "Boston", "Pittsburg", "Hartford" },
                { "Saint Paul", "Fargo", "Minot", "Chicago"},
                {"San Diego", "LA", "Berkeley", "San Franscisco" },
                { "Houston", "Dallas", "Austin", "El Paso", "Arlington"}};

        for(int i = 0;i<cities.length;i++){
            for(int j = 0;j<cities[i].length;j++){
                System.out.print(cities[i][j]+"\t");
            }
            System.out.println();
        }
    }
