Please Solve the Question by Using Java Programming and do exactly as per the question asked......

Answer 1

The code is

public class Test

{

public static int WordCount(String s)

{

if(s.equals(""))return 0;

int count=1;

int index=s.indexOf(' ');

while(index!=-1)

{

count++;

index=s.indexOf(' ',index+1);

}

return count;

}

public static String arrayToString(char[] arr)

{

String s="";

for(char c:arr)

s+=c;

return s;

}

public static char mostFrequent(String s)

{

int count[] =new int[26];

for(int i=0;i<26;i++)count[i]=0;

char[] arr=s.toCharArray();

for(char c: arr)

{

if(c!=' ')

count[c-'a']++;

}

int m=0;

int c1=0;

for(int i=0;i<26;i++)

{

if(count[i]>c1)

{

c1=count[i];

m=i;

}

}

return (char)(m+'a');

}

public static String replaceSubstring(String s,String a,String b)

{

return s.replaceAll(a,b);

}

public static void main(String[] args)

{

String string1="the dog jumped over the fence";

String string2="the";

String string3="that";

System.out.println("Number of words in \""+string1+"\" is "+WordCount(string1));

System.out.println("Most frequently occuring character: "+mostFrequent(string1));

System.out.println(replaceSubstring(string1,string2,string3));

System.out.println("How now brown cow");

}

}
