Android For loop

Question

I have the following code...

String t = " "; 
for(int l=0; l<=5; l++){
    t = "Num: " + l + "\n";
}

VarPrueba.setText(t);

I am wanting to loop through a set of numbers, and generate a String that lists them all at the end. The output should be something like this...

1
2
3
4
5

Could someone please help me understand how to correct my code.

Answer 1

Change as follow:

t+="Num: " + l + "\n";

And the most effective way to do this is to using StringBuilder, Something like:

StringBuilder t = new StringBuilder(); 
for(int l=0; l<=5; l++){
    t.append("Num:");
    t.append(l+"\n");
}

VarPrueba.setText(t.toString());
