Explanation / Answer

31. && operator is not defined for int variables. it is used with boolean variables. the error is that && can not be used with int a1 and int a2;

32. AND is not an operator in java. so error is AND operator.

33. if(a1==4); the logical error is using semi colon after if(); it means that the statement after if() is not excuted based on if condition. the statement after if() is executed each time. it treats semicollon as one statement;

34. if b1==true is not a valid java statement. but if(b1==true) is. so braces are must.

35. if{b2==true} is not a valid statement. but if(b2==true) is. if condition uses braces not curly braces.

36. else if() statement can not be after else statement but it can be before else statemet;

37. it has not errors;

38. it does not have any error.
