So I am having trouble knowing what to return in the bottom method any help would be appreciated .
Here are the specifications for completing the StringArray class:
(a) In the class StringArray write method numInArray,using the method signature below. numInArray should return the number of times the string s occurs in array a.
For example, assume that array a is as shown below.
[0] [1] [2] [3] [4] [5] [6]
java is nice so nice it is
Here are some examples of calls to method numInArray.
Method call Returned value
numInArray(a, "java") 1
numInArray(a, "is") 2
numInArray(a, "nice") 2
numInArray(a, "ja") 0
Complete method numInArray below.
// postcondition: returns the number of times s occurs in a
public static int numInArray(String[] a, String s)
< your code goes here >
b) Again using the class StringArray write method printAllNums,using the method signature below. For every string s in array a, printAllNums should return the string s, followed by a colon and a space, then followed by the number of times that string occurs in array b. Use the \n control character to print a new line at the end of each line.
For example, assume that arrays a and b are as shown below.
[0] [1] [2] [3]a: ice cream is nice
[0] [1] [2] [3] [4] [5] [6]b: java is nice so nice it is
The call printAllNums(a, b) should produce the following string:
ice: 0
cream: 0
is: 2
nice: 2
In writing printAllNums, you will probably want to utilize the method numInArray, presuming that it works properly.
Complete method printAllNums below.
// postcondition: for all k such that 0 <= k < a.length,
// returns the string in a[k] followed by a colon
// and a space and the number of times that string
// occurs in b. (\n is used to generate a new line)
public static String printAllNums(String[] a, String[] b)
< your code goes here >
public class StringArray
{
public static int numInArray(String[] a, String s)
{
int count = 0;
for(int i = 0; i < a.length; i++)
{
if (s.equals(a[i]))
{
count++;
}
}
return count ;
}
public static String printAllNums(String[] a, String[] b)
{
for (String aString : a){
System.out.println(aString + ": " + numInArray(b, aString));
}
return ;
}
}
