Create a method called firstLetter that takes a String parameter and integer parameter. It should return -1 if the number of words in the given String is greater than or equal to the integer parameter (it should return -1 and not process the String any further) (4 points). If the String does not have more words than the given integer, the method should return 1 if all the words in the string start with the same letter(8 points) and 0 if all the words do not start with the letter(4 points). (4 points: correct method signature-2 for parameter, 2 for return type) For example, System.out.println(firstLetter("Charlie chews chewy chews.",10)); would print to screen 1 since all words start with the same letter (notice the method is not case sensitive) and the number of words is less than 10.

Method code

public static int firstLetter(String str, int n)
{
String words[]=str.split(" ");
if(words.length>=n)
return -1;
for(int i=0;i<words.length-1;i++)
if(Character.toUpperCase(words[i].charAt(0))!=Character.toUpperCase(words[i+1].charAt(0)))
return 0;
return 1;
}
  

for testing i created this simple program


public class Main {

/**
* @param args the command line arguments
*/
public static void main(String[] args)
{
System.out.println("firstLetter(\"Charlie chews chewy chews.\",10))="+firstLetter("Charlie chews chewy chews.",10));
System.out.println("\nfirstLetter(\"Charlie chews chewy chews.\",3))="+firstLetter("Charlie chews chewy chews.",3));
System.out.println("\nfirstLetter(\"Charlie chews jay chews.\",10))="+firstLetter("Charlie chews jay chews.",10));
}

public static int firstLetter(String str, int n)
{
String words[]=str.split(" ");
if(words.length>=n)
return -1;
for(int i=0;i<words.length-1;i++)
if(Character.toUpperCase(words[i].charAt(0))!=Character.toUpperCase(words[i+1].charAt(0)))
return 0;
return 1;
}
  
}

output

Write a static method called "evaluate" that takes a string as a parameter
In Java language  Write a static method called "evaluate" that takes a string as a parameter. The string will contain a postfix expression, consisting only of integer operands and the arithmetic operators +, -, *, and / (representing addition, subtraction, multiplication, and division respectively). All operations should be performed as integer operations. You may assume that the input string contains a properly-formed postfix expression. The method should return the integer that the expression evaluates to. The method MUST use a stack...
