Question

I am trying to create a float[] depending on the user selection. In the code below, the variable widths is not recognized outside the if block. How can I dynamically create a float[] or append a float[]?

if(!dangerCheckBox.isSelected()){
    float[] widths = {100, 250, 70};
} else {
    float[] widths = {100, 250, 70, 70};
}

Answer 1

Just put it outside.

    float[] widths;        

    if(!dangerCheckBox.isSelected()){
        widths = new float[] {100, 250, 70};
    } else {
        widths = new float[] {100, 250, 70, 70};
    }
