Expert Solution & Answer
Chapter 5, Problem 2PE
Explanation of Solution
The Java method to display “ResultSet” as a table is given below,
“ResultSetTable()” method:
ResultSetTable(ResultSet rt) throws SQLException
{
//Declare the variable for JDBC meta data
ResultSetMetaData meta_data;
//Declare the variable for number of columns in result
int columns;
//Get the meta data
meta_data=rt.getMetaData();
//Get the columns count
columns=meta_data.getColumnCount();
//Create "for" loop
for (int i; i<=columns; i++)
{
//Get the column header and outputs them
System.out.print(meta_data.getColumnName(i)+" ");
}
//Print new line
System.out.println();
//Execute "while" loop for current record
while(rt...

- Specifications: Part-1Part-1: DescriptionIn this part of the lab you will build a single operation ALU. This ALU will implement a bitwise left rotation. Forthis lab assignment you are not allowed to use Digital's Arithmetic components.IF YOU ARE FOUND USING THEM, YOU WILL RECEIVE A ZERO FOR LAB2!The ALU you will be implementing consists of two 4-bit inputs (named inA and inB) and one 4-bit output (named out). Your ALU must rotate the bits in inA by the amount given by inB (i.e. 0-15).Part-1: User InterfaceYou are provided an interface file lab2_part1.dig; start Part-1 from this file.NOTE: You are not permitted to edit the content inside the dotted lines rectangle. Part-1: ExampleIn the figure above, the input values that we have selected to test are inA = {inA_3, inA_2, inA_1, inA_0} = {0, 1, 0,0} and inB = {inB_3, inB_2, inB_1, inB_0} = {0, 0, 1, 0}. Therefore, we must rotate the bus 0100 bitwise left by00102, or 2 in base 10, to get {0, 0, 0, 1}. Please note that a rotation left is…arrow_forwardSolve this "Do not use AI tools.

- Specifications: Part-2Part-2: DescriptionIn this part of the lab, we will illuminate two 7-segment displays. You will need to understand 2's Complement todetermine when the input 4-bit binary number corresponds to a negative or positive number. To understand how anLED display works in Digital, please refer to the playWithLED_Display.dig file provided. You should play withdifferent input combinations to see how it influences the LED Display value. In the screenshot below, note how I wasable to generate the display of “3” on the Hex display by lighting up only certain input wires to the unit. Here is a picture of how the different segments light up to produce the different displays: Note in the picture above that we showed displays only from 0-8 since in 4-bit 2s complement representation, 8 is thelargest modulus value you can represent (the range of integers would be -8 to +7).Your circuit in Part-2 must accept a 4-bit 2's complement input {in3, in2, in1, in0} where in3 is the most…arrow_forwardSolve this "Do not use AI tools.
