Answer 1

//with .toUpperCase();

public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("votre texte:");
String texte = sc.nextLine();
System.out.println(texte);
System.out.println("________________________");
String textenum = texte.toUpperCase()
.replace("A","4")
.replace("E","3")
.replace("I","1")
.replace("T","7")
.replace("O","0")
.replace("B","8")

System.out.println(textenum);
