Enjoy .
Write a Program to use if - else in Java
Open notepad or any text editor and type this code.
public static void main(String args[])
{
int a=5,b=8;
System.out.print("2 nos. are: "+a+" and "+b+"\n");
if(a>b)
{
System.out.print("Bigger no is:"+a);
}
else
{
System.out.print("Bigger no is:"+b);
}
}
}
and save this file as example.java in the bin directory (c:\j2sdk1.4.2\bin).
public static void main(String args[])
{
int a=5,b=8;
System.out.print("2 nos. are: "+a+" and "+b+"\n");
if(a>b)
{
System.out.print("Bigger no is:"+a);
}
else
{
System.out.print("Bigger no is:"+b);
}
}
}
and save this file as example.java in the bin directory (c:\j2sdk1.4.2\bin).
Now open command prompt and go to your Java directory.
Now compile your program by typing javac ifelse.java
Now the program will be compiled.
Now Run your program by typing java ifelse
The output of the above program will be like this.
Write a Simple Java Program
