Please help with coding problem

Question

Hello,

I have a question about a java code. I have to write a program where i'll enter a String value as a variable “word”: “blahblahblah” then create a method that is called “showPairs(String word)” 

In the method, the program must show us “word” that is separated by 4 characters (we don't need to consider last two characters). The only thing I'm confused about is how to show the word separated into 4 characters. Please help.

I do not understand the specification, but hope this helps.

// This code prints the characters of word in groups of 4

// separated by blanks.

// If word length is not divisible by 4 then

// the last group will be shorter.

int wordLen = word.length();

int groupStart; // Index of the first character of a group

int groupEnd; // Index of the first character just beyong the group

for(groupStart = 0; // Start at beginning of word

groupStart < wordLen; // Done when group would start too far

groupStart = groupEnd) { // Next group starts where this one ended

// Calculate groupEnd

groupEnd = groupStart+4; // Normally distance 4

if (groupEnd >= wordLen)

groupEnd = wordLen; // Shorter distance for last group

System.out.print(word.substring(groupStart,

groupEnd) + " "); // print the group

}

System.out.println(""); // Terminating newLine character
