Answer 1

Try to make indents in code with correct length.

YOUR CODE:

if ( myArr[x]>=0 && myArr[x]<=100){
sum+= myArr[x]; //The sumation of degree

if (myArr[x]>=50){
System.out.println("Lesson"+ x+" = "+ myArr[x]+" Pass");}
//If there is a degree larg than 50%

else {
System.out.println("Lesson"+ x+" = "+ myArr[x]+" Fail");
}
}
else
{
System.out.println("ERROR");

}
}

SHOULD BE:

if (myArr[x]>=0 && myArr[x]<=100) {
sum+= myArr[x]; //The sumation of degree
if (myArr[x]>=50)
System.out.println("Lesson"+ x+" = "+ myArr[x]+" Pass");
else
System.out.println("Lesson"+ x+" = "+ myArr[x]+" Fail");
}
else
System.out.println("ERROR");

Answer 2

I've tweaked it a bit:

1) Better layout (as mentioned by Bartosz Pieszko)
2) Better variable names
3) Added comments
4) Corrected spelling mistakes
5) Created a function pass_or_fail () to make code clearer
6) Found issue (see FIXME section in comments)

Other points:
7) You did a code review (us), that's a good professional move
8) You could write unit tests, to test code

It can be improved further, especially what to do with bad data.

This input will give a divide by zero problem:
int [] markArray = {};

Also, instead of putting all your functionality into main(), create a new function, and call that from main. Create a function that can be unit tested.

Answer 3

No way dude lol. I spent an hour answering and gave much more details! 😂
