replaceAll Java method to remove “\\n” from String [duplicate]

Answer 1

You basically have two choices, both of which are in the below code:

public static void main(String[] args) {
    String value = "\"iVBORw0KGgoAAAANSUhEUgAAAwoAAADwCAYAAACg2ZPDAAAABHNCSVQICAgIfAhkiAAAIABJREFU\\neJzt3XecXVW99";
    System.out.println(value.replace("\"", "").replace("\\n", ""));
    System.out.println(value.replaceAll("\"|\\\\n", ""));
}

Answer 2

You could try this:

public static void main(String[] args) {
    String value = "\"iVBORw0KGgoAAAANSUhEUgAAAwoAAADwCAYAAACg2ZPDAAAABHNCSVQICAgIfAhkiAAAIABJREFU\\neJzt3XecXVW99";
    String filtre1 = value.replaceAll("\"", "");
    String filtre2 = filtre1.replaceAll("\\\\n", "");
    System.out.println(filtre2);

}

Answer 3

Maybe:

String filtre2 = filtre1.replaceAll("\\n", ""); 

need to be :

String filtre2 = filtre1.replaceAll("\\\\n", "");
