I'm trying to make a program that can compute the grade of students, Lab and Nonlab subject.
This is what I've made so far,

```
    String nonlab,lab,choices;
    String quiz1,recitation1,act1,exam1;
    int choice;
    int q1,r1,a1,e1,cs1,gr1,eq1,LAB,lec,six;

    System.out.println("CHOOSE GRADE COMPUTATION");
    System.out.println("[1] NON-LAB COMPUTATION");
    System.out.println("[2] LAB SUBJECT");

    System.out.print("ENTER YOUR CHOICE: ");
    choices=input.readLine();
    choice=Integer.parseInt(choices);

    System.out.println("     ");

    //NON LAB
    if (choice==1){
        System.out.println("******* BEGIN COMPUTATION *******");

    System.out.print("ENTER QUIZ: ");
    quiz1=input.readLine();
        q1=Integer.parseInt(quiz1);

    System.out.print("ENTER RECITATION: ");
    recitation1=input.readLine();
        r1=Integer.parseInt(recitation1);

    System.out.print("ENTER ACTIVITY: ");
    act1=input.readLine();
        a1=Integer.parseInt(act1);

    System.out.print("ENTER MAJOR EXAM: ");
    exam1=input.readLine();
        e1=Integer.parseInt(exam1);

    System.out.println("     ");
    System.out.println("********** RESULT ***************");

    cs1 = (q1+r1+a1)/3;
    gr1 = ((cs1*2)+e1)/3;

    System.out.println("CLASS STANDING: "+cs1);
    System.out.println("GRADE: "+ gr1);
    System.out.print("EQUIVALENT: ");
        if (gr1>97)
            System.out.println("1.00");
        else if (gr1>=94)
            System.out.println("1.25");
        else if (gr1>=91)
            System.out.println("1.50");
        else if (gr1>=88)
            System.out.println("1.75");
        else if (gr1>=85)
            System.out.println("2.00");
        else if (gr1>=82)
            System.out.println("2.25");
        else if (gr1>=79)
            System.out.println("2.50");
        else if (gr1>=76)
            System.out.println("2.75");
        else if (gr1<=75)
            System.out.println("5.00");

    System.out.print("REMARKS: ");
        if (e1<75)
        System.out.println("FAILED");
            else if (e1>75)
        System.out.println("PASSED");
        }

    //LAB SUBJECT
    else if (choice==2){
            System.out.println("******* BEGIN COMPUTATION *******");

    System.out.print("ENTER QUIZ: ");
    quiz1=input.readLine();
        q1=Integer.parseInt(quiz1);

    System.out.print("ENTER RECITATION: ");
    recitation1=input.readLine();
        r1=Integer.parseInt(recitation1);

    System.out.print("ENTER ACTIVITY: ");
    act1=input.readLine();
        a1=Integer.parseInt(act1);

    System.out.print("ENTER MAJOR EXAM: ");
    exam1=input.readLine();
        e1=Integer.parseInt(exam1);

    System.out.println("     ");
    System.out.println("********** RESULT ***************");

    cs1 = (q1+r1)/2;
    lec = ((cs1*2)+e1)/3;
    six = lec*(0.60);
    LAB = a1*(0.40);
    gr1 = 60%+LAB;

    System.out.println("CLASS STANDING: "+cs1);
    System.out.println("GRADE: "+ gr1);
    System.out.print("EQUIVALENT: ");
        if (gr1>97)
            System.out.println("1.00");
        else if (gr1>=94)
            System.out.println("1.25");
        else if (gr1>=91)
            System.out.println("1.50");
        else if (gr1>=88)
            System.out.println("1.75");
        else if (gr1>=85)
            System.out.println("2.00");
        else if (gr1>=82)
            System.out.println("2.25");
        else if (gr1>=79)
            System.out.println("2.50");
        else if (gr1>=76)
            System.out.println("2.75");
        else if (gr1<=75)
            System.out.println("5.00");

    System.out.print("REMARKS: ");
        if (e1<75)
        System.out.println("FAILED");
            else if (e1>75)
        System.out.println("PASSED");
    }
    else (choice>=3)
        System.out.println("WRONG ENTRY!");

}

```

}

I've been receiving an error which says: are not a statement

```
        else (choice>=3)
             ^
';' expected
        else (choice>=3)

```

... When I tried removing the else statement, these are the errors that appear:

```
possible loss of precision
found   : double
required: int

six = lec*(0.60);
          ^

possible loss of precision
found   : double
required: int

    LAB = a1*(0.40);
                ^

```

Where did I go wrong?
