Intro to Java Programming

Java Array

1. You will hand in TableAnalyzer.java for this assignment. 2. Write a value method readRow(int numColums) which returns an array of double whose length is numColumns. readRow will prompt the user to enter numcolumns numbers, followed by a return. After the prompt, readRow will also read in numcolumns numbers input by the user. 3. A void method analyzeData() will call readRow) repeatedly to read in rows of data. analyzeData) will use arrays to analyzeba calculate the mean (average) and variance for every column of the table and report the values. Sample I/O is shown below. analyzeData will prompt the user to continue or terminate data entry as shown below. Note in the sample run below how it is in the form of a yeso question that can be asked near the end of every iteration. How many columns will your table contain? 3 Please enter 3 numbers followed by Return: 1.0 1.4 2.0 ill you enter another row? (yeso) yes Please enter 3 numbers followed by Return: 1.0 2.6 3.0 Will you enter another row? (yeso) yes Please enter 3 numbers followed by Return: 1.0 3.8 4.0 ill you enter another row? (yeso) nd You entered 3 rows of data. The mean of column 0 is 1.0 and variance 0.0 The mean of column 1 is 2.6 and variance 1.0 The mean of column 2 is 3.0 and variance 0.7
