        for(int i=0;i<e-1;i  );{
            System.out.print("*");
        }
        System.out.println();
    }
    
}

the output gives only one asterisk per line instead of required the number of scanned quantity

Fix

Remove the semicolon, and change the bound from a-1 to a to have the good amount

for (int i = 0; i < a; i  ) {
    System.out.print("*");
}

Improve

With String.repeat

System.out.println("*".repeat(a));
System.out.println("*".repeat(b));
System.out.println("*".repeat(c));
System.out.println("*".repeat(d));
System.out.println("*".repeat(e));
