How do I get the size of a Java String?

Question

I’m creating a fake bank in java but I don’t know how to check if the password has 8 characters.

public void criarSenha(){
 String senhacriada = (JOptionPane.showInputDialog("Qual a senha ?"));
       if(tamanhodasenhacriada >= 8) {       //! O problema está aqui !
   System.out.println("Senha criada com sucesso !"); 
 }else {
   System.err.println("senha >= 8 !"); 
 }
}

How do I find the size of the string ?

In javascript i do :

if(lenght(senha) >= 8){
// Codigo
}

But in Java I don’t know because I’m starting to learn !

Answer 1

Use the method length(), for this will return the size of a string in characters.

Your code will stay:

if(senhacriada.length() >= 8) {       //! A solução está aqui !
   System.out.println("Senha criada com sucesso !"); 
 }else {
   System.err.println("senha >= 8 !"); 
 }
