getClassLoader().loadClass与Class.forName的区别 实例

package com;

public class User {
	private String username;

	static {
		System.out.println("this is static block");
	}

	public String getUsername() {
		return username;
	}

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

	@Override
	public String toString() {
		return "User [username=" + username + "]";
	}

}
