Can you simplify my code? (shows how many poeple liked something like on instagram)

Question

Hi guys, do you think I could change something or simplify this Code somehow? (Java):
public Name() {

for (int i = 0; i >= 0; i++) {
name = sc.nextLine();
if (check(name)==true){
names.add(name);
}
if (names.size()==0) {
System.out.println("No one likes this");
}else{
if (names.size() == 1) {
System.out.println(names.get(0) + " likes this");
} else if (names.size() == 2) {
System.out.println(names.get(1) + " and " + names.get(0) + " like this");
} else if (names.size() == 3) {
System.out.println(names.get(2) + " and " + names.get(1) + " and " + names.get(0) + " like this");
} else {
int hinten = names.size() - 2;
System.out.println(names.get(names.size() - 1) + ", " + names.get(names.size() - 2) + " and " + hinten + " others like this");

} } } }

public boolean check(String name) {
for(char c: name.toCharArray()) {
if(c>='a'&&c<='z') {
continue;
}
if(c>='A'&&c<='Z') {
continue;
}
if(c=='ä'||c=='ö'||c=='ü'||c=='Ä'||c=='Ö'||c=='Ü'||c=='ß') {
continue;
}
return false;
}
return true;
}
}

Answer 1

Yanic this is how I tried to simplify your code

Answer 2

this is readable

String and = " and ";
int size = names.size();

String who =
switch( size) {
case 0 -> "No one";
case 1 -> names.get(0);
case 2 -> names.get(1) +and+ names.get(0);
case 3 -> names.get(2) +and+ names.get(1) +and+
names.get(0);
default -> names.get( size-1) +", "+
names.get( size-2) +and+
(size-2) +" others";
};
System.out.println( who +" like this");

What are you trying to do?

ɴᴜʟʟ thanks! That looks good. Gonna try this in a moment :D

Answer 5

first correct for()

import java.util.*;

public class Name {
Scanner sc = new Scanner( System.in);
ArrayList<String> names = new ArrayList<>();
String name;

public static void main(String[] args) {
new Name();
}
public Name() {
//for (int i=0; i >= 0; i++) {
for (int i=0; i < 5; i++) {

Answer 6

sorry i couldnt write everything because of the character restrictions. I am trying to make a code where i can type in random names and based on the names and number of names it gives me an output like this:
[] --> "no one likes this"
["Peter"] --> "Peter likes this"
["Jakob", "Jan"] --> "Jakob and Jan like this"
["Max", "Jan", "Jens"] --> "Max, Jan and Jens like this"
["Jan", "Jakob", "Jens", "Max"] --> "Jan, Jakob and 2 others like this"
