IF ELSE statement sample program

This program will compute the 3 grades and get the average. the program will show a message "Your Passed" if the average is 75 above. else the program will show a message " Your Failed" if the average is Below 75.

here is the program.

{
public static void main(String args[])
{
//declaration of variables
int math=90;
int PE=90;
int prog=95;
int ave=0;

//Compute the average

ave=(math + PE + prog)/3;

//display the average
System.out.print("Your average is:" + ave);


//checking the average if it is 75 above or below 75 using if statement

if(ave>=75)
{
System.out.print("Your Passed");
}
else
{
System.out.print("Your Failed");
}

}
}

{
//declaration
int age=18;

if(age>=18)
   {
     System.out.println("Your Qualified to Vote");
    }
else
   {
