Hello The java function belw is generating a NullPointerException.

Language: Java Rewrite the ADA source code in Java.Within the Java version of the code, change the second half of the first loop so that all assignments to the counting array 'Freq()' are updated in the EXCEPTION portion of the code. There should be no valid updates to 'Freq()' anywhere else in the loop.ADA source code:with Ada.Text_IO , Ada.Integer_Text_IO ;use Ada.Text_IO, Ada.Integer_Text_IO;procedure Grade_Distribution isFreq: array (1..10) of Integer := (others => 0);New_Grade : Natural;Index,Limit_1,Limit_2 : Integer;beginGrade_Loop:loopbeginGet(New_Grade);exceptionwhen Constraint_Error =>exit Grade_Loop;end;Index := New_Grade/10 + 1;beginFreq(Index) := Freq(Index) +1 ;exceptionwhen Constraint_Error =>if New_Grade = 100 thenFreq(10) := Freq(10) + 1;elsePut("Error -- new grade: ");Put(New_Grade);Put(" is out of range");New_Line;end if;end;end loop Grade_Loop;Put("Limits Frequency");New_Line; New_Line;for Index in 0..8 loopLimit_1 := 10 * Index;Limit_2 := Limit_1 + 9;if…

In JAVA, write a program in a single file that: Main: Creates 10 random doubles, all between 1 and 11, Calls a method that writes 10 random doubles to a text file, one number per line. Calls a method that reads the text file and displays all the doubles and their sum accurate to two decimal places. SAMPLE OUTPUT 10.62691196041722.7377903389094555.4279257388651281.37420580654725091.18587002624988364.1803912764852284.9109699989306755.7108582343439587.7908570073730523.1806714736219543 The total is 47.13
In the Utils class provided to you in this exercise, please fill in the details for a method called swapArray(). You can either upload a file or use the Edit tab to submit your work. The VPL tester will pass an arbitrary array of type integer to your method, along with the value of the locations in the array of two values that need to be swapped (exchanged). For instance, in the illustration below, the method swapArray is told to swap the values in positions 0 and 2 of an array made up of {10, 20, 30, 40, 50}. The three input parameters to the method are the array, as well as the two array indices (i and j) that control which elements to swap. Your task is to write the contents of the method that can execute this swap.
I need to write a program called Table.Java that takes a command line argument N and prints a table of N rows with a header as shown in the example below (not including the last line). The table has 6 columns and there is a gutter of one space between the columns. Column 1 (7): the number I, decimal, right justified, separate 1000s with commas Column 2 (6): the number I, hexadecimal, four digits, zero-padded (add one space before this column) Column 3 (9): the number I*I, decimal, right justified, separate 1000s with commas Column 4 (9): the number I*I*I, decimal, right justified, separate 1000s with commas Column 5 (9): the log base 2 of I*I, rounded to three digits right of decimal point, right justified Column 6 (8): the percent of rows completed (rounded to the nearest integer percent) (the size is 8 including percentage sign, make the whole thing right justified) Numbers in parenthesis are column sizes. For the command: java Table 10 Output is shown below
Given the following Java functions, transcribe it into a Python 3 program. /*** Rehashes the contents of this hash table into a new array with a* larger capacity.
