How to return lambda as an object?

package com.java2novice.lambda;

public class Employee {

	private String name;
	private String account;
	private Integer salary;

	public Employee(String name, String account, Integer salary) {
		super();
		this.name = name;
		this.account = account;
		this.salary = salary;
	}

	@Override
	public String toString() {

		return "name: "+ this.name +" | account: "+ this.account +" | salary: "+this.salary;
	}

	public String getName() {
		return name;
	}

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

	public String getAccount() {
		return account;
	}

	public void setAccount(String account) {
		this.account = account;
	}

	public Integer getSalary() {
		return salary;
	}

	public void setSalary(Integer salary) {
		this.salary = salary;
	}
}

package com.java2novice.lambda;

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;

public class LambdaAsObjectEx {

	public static void main(String a[]) {

		LambdaAsObjectEx.sortInLambdaWay(empList);
	}
