If int y =10 then find int z = (++y * (y++ + 5));

What is the value of y after the execution?
y+= ++y + y-- + --y; when int y=8

What will be the output of the following code?

int k=5,j=9;
k+= k++ - ++j + k;
System.out.println("k="+k);
System.out.println("j="+j);

Rewrite the following program segment using if-else statements instead of the ternary operator:

String grade = (marks>=90)?"A": (marks>=80)? "B": "C";
