Question

I have a matrix of objects that contains data in this form:

name A,2,name B
name C,3,name D
name E,4,name F
name G,5,name H

My code to process the data is:

for (int i = 0; i < numRow; i++) {
    for (int j = 0; j < numColumn; j++) {
        Object o = matrix[i][j];
        String x = o.toString();
    }
}

In this way, x assumes these values in turn:

name A,
2,
name B,
name C,
3
name D,
name E,
...

and so on.

From the table I must create a linked list of objects Expression(String, int, String),
for example:

Expression a = new Expression("name A", 2, "name B")

How could I extract the data from matrix in the right way to do this?

Answer 1

Do you mean something like this?

String[][] matrix = { 
        { "name", "2", "name" }, 
        { "name", "2", "name" },
        { "name", "2", "name" }, 
        { "name", "2", "name" }, 
};

List<Expression> list=new LinkedList<Expression>();
for (int i = 0; i < matrix.length; i++) 
    list.add(new Expression(matrix[i][0], Integer.parseInt(matrix[i][1]), matrix[i][2]));
