How to read text file into array

Merlin04

I just started this morning with Processing. I want to be able to take a text file:

Hello world
abc
123

And get this:

["Hello World", "abc", "123"]

How can I do this?

Thanks! But now I have another question. This code:

  String colours[] = loadStrings("colors.txt");
  for ( int i = 0 ; i < colours.length; i++ ) {
    colour = colours[i];
    println(colour);
    if (colour == "blue") {
      r = 4;
      g = 158;
      b = 247;
      println("blue");
    }
    else if (colour == "red") {
      r = 252;
      g = 71;
      b = 55;
      println("red");
    }
    else if (colour == "green") {
      r = 55;
      g = 252;
      b = 127;
      println("green");
    }
    else {
      r = 252;
      g = 252;
      b = 252;
    }
    background(r,g,b);

is supposed to set the background color based off of a text file called colors.txt. However, the background is always white. Why is this happening?

if (colour.equals("blue") )

Not sure but when you want to see multiple different colors from a text file you need to change the for loop and use draw to display them
