double Percentage = (100/450) * Total;

System.out.println("Your total percentage is " + Percentage +"%");
                 }
 }

Sorry for the extremely clumsy code, I'm really new to this.

So I checked the code again and again, and while there seem no issues, after it takes all inputs correctly, the percentage still comes out to be 0.0%. I have no idea why.

    try:
    line 159 change (100/450) to (100.0/450.0)

    why:
    100 and 450 are integers so 100/450 = 0
