int z[] =new int[]{i,j,k};
Arrays.sort(z);

if(e.getActionCommand()=="最大值"){
jtf4.setText(z[2]+"");
}
else if(e.getActionCommand()=="最小值"){
jtf4.setText(z[0]+"");
}
}

}

public static void main(String[] args) {

JFrame jf = new JFrame();
jtf1 = new JTextField();
jtf2 = new JTextField();
jtf3 = new JTextField();
jtf4 = new JTextField();

JButton button1 = new JButton("最大值");
JButton button2 = new JButton("最小值");

button1.addActionListener(new myListener());
button2.addActionListener(new myListener());
jf.setLayout(new GridLayout(3,3));
jf.add(jtf1);
jf.add(jtf2);
jf.add(jtf3);
jf.add(jtf4);
jf.add(button1);
jf.add(button2);
jf.setSize(500, 500);

import java.util.Scanner;
class zuizhi
{
public static void main(String[] args)
{
Scanner reader=new Scanner(System.in);
System.out.println("请输入第一个数");
double a=reader.nextDouble();
System.out.println("请输入第二个数");
double b=reader.nextDouble();
System.out.println("请输入第三个数");
double c=reader.nextDouble();
double d=a>b?a:b;
double e=d>c?d:c;
double f=a<b?a:b;
double g=f<c?f:c;
System.out.println("最大的是"+e+"最小的是"+g);
}
}
