DELETE and PUT in AndroidStudio with HttpUrlConnection

I have a REST API from a user database made in NodeJS, the address to use the GET method is http://localhost:3000/users/ the method DELETE and PUT receive a parameter that is concatenated in the same address, http://localhost:3000/users/2 where the last one is the id of the user that I want to delete or edit.

I am developing the application on Android using HttpUrlConnection and Asynctask , but it is difficult for me in that part, I can not send the parameter in the url.

UserModel.java

package muse.pe.com.s13s01pedroso.model;

public class UsuarioModel {

private int id;
private String username;
private String email;
private String password;
private String create;
private String updated;

public UsuarioModel() {
}

public UsuarioModel(int id) {
    this.id = id;
}

public UsuarioModel(int id, String username, String email, String password, String create, String updated) {
    this.id = id;
    this.username = username;
    this.email = email;
    this.password = password;
    this.create = create;
    this.updated = updated;
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

public String getUsername() {
    return username;
}

public void setUsername(String username) {
    this.username = username;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

public String getCreate() {
    return create;
}

public void setCreate(String create) {
    this.create = create;
}

public String getUpdated() {
    return updated;
}

public void setUpdated(String updated) {
    this.updated = updated;
}
}
