how to make a loop of a switch statement with a label in java

it's quite simple but i don't seem to fegure it out here is my code 

System.out.println("1=>do this \n2=> do that \n3=> blablabla \n4=> EXIT");


choose:{
int choix = s.nextInt();
switch (choix) {
case 1 : lper.addpersonne(); 
     break choose;
case 2 : lper.removepersonne();
     break choose;
case 3 : blalalalala

when it comes to execution

the "lper.addpersonne" works perfectly fine but after that i can't get the label where i can choose something else . it just stops

Why not clean that code up a bit and use something along these lines?

int choix;
do {

    System.out.println("1=>do this \n2=> do that \n3=> blablabla \n4=> EXIT");
    choix = s.nextInt();
    switch (choix) {
    case 1 : lper.addpersonne(); 
        break;
    case 2 : lper.removepersonne();
        break;
    case 3 : blalalalala
        break;

} while (choix != 4);

This way you don't have to worry about the for loop, it repeats until the user wants to quit, and you don't have to use the pesky labels.

boolean loop = true;
while(loop){    
System.out.println("1=>do this \n2=> do that \n3=> blablabla \n4=> EXIT");
choose:{
    int choix = s.nextInt();
    switch (choix) {
    case 1 : lper.addpersonne(); 
        break choose;
    case 2 : lper.removepersonne();
     break choose;
    case 3 : blalalalala
    .... //What do you want more
    }
if(choix == 4){loop = false;}
}

}
