May be use ***.propeties to store these projest parameter .

Why you still use 'System.err.println(),System.err.print, System.out.println()' , use logger instend .

Please check if you have use really manager user .

The table have one editable column 'Amount',
then input 1500 in the 'Amount' column, select the first row of this column ,press enter, the cursor goes to the next row 'Amount' column, try to type 1450 in the second row 'Amount' column, but on the screen, it shows 15001450


How can solve this problem.(get the value 1450).

Saket

sure , you can encourage yourself with adequate supplies.

public class Foo { Foo() { System.out.print("foo"); } class Bar { Bar() { System.out.print("bar"); } public void go() { System.out.print("hi"); } } public static void main(String[] args) { Foo f = new Foo(); f.makeBar(); } void makeBar() { (new Bar() { public void go() { System.out.print("HIT"); }}).go(); } }
Result : foobarHIT
I hope this can help you .

According to me, arithmetic operations preceed over binary shift operators , taking this into account, the answer to i is 0 but when I run , I get an answer 3.

This is how I evaluated.
int i = ((4*6)-(3/2))<<2*5>>>((1%2)-(4^3))
int i = 23<<10>>>-2
int i = 23552>>>-2
int i = 0

Now, what is wrong ???

Of cource ,it's wrong .
PRI : Unary > Arithmetic > Relational > Logical > Conditional > Assignment.
*/+-<<>>> are Arithmetic ,and ^ is Logical .
SO:
int i = 24-1<<10>>>2-4^3
i = 23<<10>>2-4^3
i = 23<<10>>-2^3
i = 0^3
I hope it can help you.

Well, that makes it harder

Expecting !!!

That's lapsus calami .

"After line 6 at least one object has more than two references "
Because t3 just have one reference t2.link.
That's be explained by Lakshmanan Arunachalam kindlly.

Leoo.

Give you some suggest.
You must know the the differences of Object and DataType....
such as Boolean and boolean.
These is the foundation of java learning.

That's right.
The test questions always have these trap.
So please be carefull.

class Parent{ public void nonStaticMethod() { System.out.println("Parent''s Non-Static Method is Called"); } public static void staticMethod() { System.out.println("parent''s static method is called"); } } class Child extends Parent{ public void nonStaticMethod() { System.out.println("child''s non-static method is called"); } public static void staticMethod() { System.out.println("child''s static method is called"); } } public class Test{ public static void main(String args[]) { Parent p1 = new Parent(); Parent p2 = new Child(); Child c = new Child(); System.out.print("Parent.static: "); Parent.staticMethod(); System.out.print("p1.static: "); p1.staticMethod(); System.out.print("p2.static: "); p2.staticMethod(); System.out.print("p1.nonStatic: "); p1.nonStaticMethod(); System.out.print("p2.nonStatic: "); p2.nonStaticMethod(); System.out.print("Child.static: "); Child.staticMethod(); System.out.print("c.static: "); c.staticMethod(); System.out.print("c.nonStatic: "); c.nonStaticMethod(); } }
After you run this programmer , you will know the reson.
"Static methods can't be overridden " , that's means the child static methods cann't overridden the parent methods when programmer
runing. the child always use parent static methods when you use it's static method.
