this one helps. From a static method main you are attempting to instantiate an inner class PieChart that is not static -- declare it static.
public static class PieChart extends JComponent { 

Is it possible to print message on console without main and static block in java?

around this issue In an interview I have asked this question:Without using static and main how could we print message on console?Is it possible? , You could define a custom class loader that prints your message :
public class MyClassLoader extends ClassLoader {
    public MyClassLoader(ClassLoader other) {
         super(other);
         System.out.println("Hi there");
         System.exit(0);
    }
}

Call a non-static method in main static method in Java

wish of those help Because this is non-static. this is an instance, and you cannot reference instance variables within a static method since static means "one for the entire class."
You should make the hasAllUniqueChars method static (like static boolean hasAllUniqueChars(String input)), so you could do
System.out.println(UniqueChars.hasAllUniqueChars(input));
System.out.println(hasAllUniqueChars(input));
UniqueChars uc = new UniqueChars();
System.out.println(uc.hasAllUniqueChars(input));

this will help You trying to use inner class in static context as static nested. So you should chenge it so static nested:
public static class sclass
UpperClassName upperClass = new UpperClassName();
sclass ss = upperClass.new sclass();
