Answer:
//importing package java.util.ArrayList to use ArrayList in the program
import java.util.ArrayList;
import java.util.Date;
public class test_array_list {
// Main method
public static void main(String[] args) {
// Create an array list of objects
ArrayList<Object> s = new ArrayList<Object>();
s.add(new Loan());
s.add(new Date());
s.add(new String("String class"));
s.add(new Circle());
// Display all the elements in the list by
// invoking the object’s to String() method
for (int element = 0; element < o.size(); element++) {
System.out.println((s.get(element)).toString());

Explanation:
The Above code has proper comments to which is self explanatory.
Answer:
if (pH<7.0){
neutral=0;
base=0;
acid=1;
}
else if (pH>7.0){
neutral=0;
base=1;
acid=0;
}
else if (pH==7.0){
neutral=1;
base=0;
acid=0;
}
Explanation:
As required by the question, if and else statements have been used to test the value of the pH and assign the apropriate values to the variables neutral, base and acid.
The code snippet below can be used to prompt the user to enter values for pH
<em>import java.util.Scanner;</em>
<em>public class pHTest {</em>
<em> public static void main(String[] args) {</em>
<em> Scanner scr = new Scanner(System.in);</em>
<em> System.out.println("Enter a value for the pH");</em>
<em> int neutral, base, acid;</em>
<em> double pH = scr.nextDouble();</em>
<em> if (pH<7.0){</em>
<em> neutral=0;</em>
<em> base=0;</em>
<em> acid=1;</em>
<em> }</em>
<em> else if (pH>7.0){</em>
<em> neutral=0;</em>
<em> base=1;</em>
<em> acid=0;</em>
<em> }</em>
<em> else if (pH==7.0){</em>
<em> neutral=1;</em>
<em> base=0;</em>
<em> acid=0;</em>
<em> }</em>
<em>} }</em>
