Hi friend,

Code to solve the problem :


class InsertWord
{
public static String insertWord(String sentence, String word, int position)
{
String sentenceAr[] = sentence.split(" ");
String strAr[] = new String[sentenceAr.length+1];
String stringResult=" ";
if(position==0)
{
System.out.println("position : " + position);
strAr[0] = word;
stringResult +=" "+strAr[0];
for(int i=1;i<strAr.length;i++)
{
strAr[i] =sentenceAr[i-1];
stringResult +=" "+ strAr[i] + " ";
}
}
else if(position!=0)
{

for(int i=0;i<position;i++)
{
strAr[i] =sentenceAr[i];
stringResult +=" "+ strAr[i];
}
strAr[position] =word;
stringResult +=" "+ strAr[position];
for(int i=position+1;i<strAr.length;i++)
{
strAr[i] =sentenceAr[i-1];
stringResult +=" "+ strAr[i];
}
}


return stringResult;

}
public static void main(String[] args)
{
String sentence ="Hello World";
String word ="Roseindia";
int position = -1;
String sentenceAr[] = sentence.split(" ");
if(!(position>sentenceAr.length || position<0))
System.out.println(insertWord(sentence, word, position));
else
System.out.println(sentence);
}
}

Thanks
