The How-Tos When It Comes To Defining, Assigning, And Printing A Java Array

How to define, assign, and print an array using Java. 🔃

Defining an array (character type) of a size 3 called arraychar [] array = new char[10]Ask user to enter 10 characters and assign each of the characters into the arrayfor (int i = 0; i < array.length; i++)

array[i] = keyboard.next().charAt(0);Use the data in array to reverse a list called reverse so that the first element in the list called array is the last element in reversefor (int i = 0; i < array.length; i++)

reverse[reverse.length – i] = array[i];Write the first use way to use for-loop to print out all elements in the list called reversefor (int i = 0; i < reverse.length; i++)

System.out.print(reverse[i] + " " );Write the second use way to use for-loop to print out all elements in the list called reversefor (char value : reverse)

System.out.print(value + " ");Define a 3 by 4 floating point values array, called scoresdouble [][] scores = new double [3][4];Assign the value for each cell in the array called scores to columnIndex * 20 / rowIndexfor (int row = 0; row < scores.length; row++)

for (int col = 0; col < scores[row].length; col++)

scores[row][col] = col * 20 / (double) row;Print all the values in the array called scoresfor (int row = 0; row < scores.length; row++) {

for (int col = 0; col < scores[row].length; col++)

System.out.print (scores[row][col] + "\t");

System.out.println();

}Write a findMax method which finds the maximum value in the data stored in scoresstatic double findMax(double [][] scores) {

double max = scores[0][0];

for (int row = 0; row < scores.length; row++)

for (int col = 0; col < scores[row].length; col++)

if (scores[row][col] > max)

max = myScores[row][col];

return max;

}
