Please use whole words, punctuation, capitals, etc. Those to whom English is not their native language find the abbreviations difficult to understand. Frankly, some of us to whom English is our native language find it difficult sometimes.

The end (close brace) if this 'if' clause is missing:

if ( gradecounter != 0 )

Indenting your code correctly would have revealed this.

Am still getting illegal start of expression

if (grade >= 40 && <= 90){
 
             System.out.println("The number of " + gradecounter + " passed the Exam" );
         }
             else {
             System.out.println("The number of " + gradecounter + "failed the exams");
          }
 
 
 
 
            }
}

this is the code
the if (grade >= 40 && <= 90) is underlined saying... illegal start of expression

Thanks guys
I have seen it that grade is missing from if (grade >= 40 && <= 90){
