Writing Java long If/Else Loops in a shorter way

Hi guys i currently have a assignment which i just finished but their is one detail i dont love about it. Is there a way to shorten if else loops

Currently i have wrote

    if (x >=300) {
        set y = 1;
    }
    else if(x >=200) {
        set y = 2;
    }
    else if (x >=150) {
        set y = 3;
    }
    else if (x>=100) {
        set y = 4;
    }
    else if (x >=50) {
        set y = 5;
    }
    else if (x >=25) {
        set y = 6;
    }

Probably me just being pedantic, thanks in advance
