import org.apache.commons.lang.builder.ToStringStyle;

public class Teacher {
	private String name;
	private int age;
	private List<Student> student;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public int getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

	public List<Student> getStudent() {
		return student;
	}

	public void setStudent(List<Student> student) {
		this.student = student;
	}

	@Override
	public String toString() {
		//return new ToStringBuilder(this,ToStringStyle.SHORT_PREFIX_STYLE).append("name", this.name).append("age",this.age).append("student",this.student).toString();
		return ToStringBuilder.reflectionToString(this,ToStringStyle.SHORT_PREFIX_STYLE);
