  3. Desafio – Aula07 • class Aluno { • private String nome; • private float nota; • public Aluno(String nome, float nota){ • this.nome = nome; • this.nota = nota; • } • public void setNota(float nota){ • this.nota = nota; • } • public float getNota(){ • return nota; • } • public String getNome(){ • return nome; • } • }

  4. Desafio – Aula07 • class Disciplina{ • private String materia; • private String professor; • public static Aluno alunos[] = new Aluno[10]; • public Disciplina (String materia, String professor) { • this.materia = materia; • this.professor = professor; • } • public Aluno procurarAluno(String aluno) { • for (int i=0; i<10; i++){ • if (aluno.equals(alunos[i].getNome())){ • return (alunos[i]); • } • } • return (null); • }

  5. Desafio – Aula07 • public void inserirAluno(Aluno aluno, int posicao){ • alunos[posicao]=aluno; • } • } • import java.util.Scanner; // Classe Scanner • class Principal { • public static void main(String args[]) { • Aluno aluno; • String disciplina="",professor="",nomeAluno=""; //inicia Strings • float nota; • Scanner entrada = new Scanner( System.in );

  6. Desafio – Aula07 • System.out.printf("\nEntre com nome da disciplina: "); • disciplina = entrada.nextLine() ; • System.out.printf("\nEntre com nome do professor: "); • professor = entrada.nextLine(); • Disciplina minhaDisciplina = new Disciplina(disciplina,professor); • for (int cont=0; cont<10; cont++){ • System.out.printf("\nDigite o nome do aluno %d: ",cont+1); • nomeAluno = entrada.nextLine(); // lê nome do aluno • aluno = new Aluno(nomeAluno,0); • minhaDisciplina.inserirAluno(aluno,cont); • } • do { • System.out.printf("\nEntre com nome do aluno a procurar: "); • nomeAluno = entrada.nextLine();

  7. Desafio – Aula07 • if (nomeAluno!="") { • aluno = minhaDisciplina.procurarAluno (nomeAluno); • if ( aluno != null) { • System.out.printf("\nNota atual: %.1f",aluno.getNota()); • System.out.printf("\nEntre com a nova nota: "); • nota = entrada.nextFloat(); • aluno.setNota(nota); • System.out.printf("\nNova nota de %s: %.1f\n", • aluno.getNome(),aluno.getNota()); • String lixo = entrada.nextLine();// consome o ENTER da nota • } • } • } while (!nomeAluno.equals("")); • System.out.printf("\nFim do programa...\n"); • } //main method • } //class Principal
