Finding largest and smallest integer

[mlhazan]

This code shows malicious behavior.Actually I dont know what is wrong.I can solve using max and min method but I have to do using if else so Pls help me.Here is my code:


import javax.swing.*;
public class Max_min {
public static void main(String[]args){
int a=0,b=0,c=0;
String numA,numB,numC;

numA=JOptionPane.showInputDialog( "Enter number A");
a=Integer.parseInt(numA);

numB=JOptionPane.showInputDialog( "Enter number B");
b=Integer.parseInt(numB);

numC=JOptionPane.showInputDialog( "Enter number C");
c=Integer.parseInt(numC);

if(a>b)
{
if(b>c){
JOptionPane.showMessageDialog(null," a is greatest and c is smallest");
}
else JOptionPane.showMessageDialog(null," a is greatest and b is smallest");

}
else if(b>a)
{
if(a>c){
JOptionPane.showMessageDialog(null," b is greatest and c is smallest");
}
else JOptionPane.showMessageDialog(null," b is greatest and a is smallest");
}
else if(c>b)
{
if(b>a){
JOptionPane.showMessageDialog(null," c is greatest and a is smallest");
}
else JOptionPane.showMessageDialog(null," c is greatest and b is smallest");

}
}
}
