Easy Solution ----- Beginner Friendly--- Rverse of Word in String...
package Programs;
import java.util.ArrayList;
import java.util.Iterator;
public class Reverseword {
public static void main(String[] args) {


String str="I love java programming";
int end=str.length();

ArrayList ar=new ArrayList();

for(int i=str.length()-1;i>=0;i--)
{
if(str.charAt(i)==' ')
{

ar.add(str.substring(i+1,end));
end=i;
}
else if(i==0)
{
ar.add(str.substring(i,end));
}

}

Iterator it=ar.iterator();

while(it.hasNext())
{
System.out.print(it.next()+" ");
}
}
}
