Write a program in java to enter a String and convert all cat to dog?

import java.io.*; class CatToDog { protected byte words(String xs) { byte a=0; for(byte i=0;i<xs.length();i++) { if(xs.charAt(i)==' ') a++; } return (byte)(a+1); } protected static void main()throws IOException { BufferedReader in=new BufferedReader(new InputStreamReader(System.in)); CatToDog o=new CatToDog(); System.out.print("Enter the String: "); String s=in.readLine(); byte a=o.words(s),b=0,c=0; String w[]=new String[a]; for(;b<a;b++) w[b]=""; for(b=0;b<s.length();b++) { if(s.charAt(b)==' ') c++; else w[c]+=s.charAt(b); } for(b=0;b<a;b++) { if(w[b].equalsIgnoreCase("Cat")) System.out.print("Dog "); else System.out.print(w[b]+" "); } }}


An alternator provides 20 A of Peak current at 100 Volts Peak AC to a resistive electric heater. How much heating power is delivered to the load A. 5 W B. 20 W C. 500 W D. 1000 W?

The answer is D. Why is it 1000W? How did you get that answer?


How can you test the vector group DYn11 and vector diagram?

connect the neutral point of the star (secondary) to u phase of primary, and now apply voltage to primary and measure the voltage between V&R, W&B, V&Y and V&B. when you measure voltage b/w 1. V&R the voltage must be maximum, 2. W&B Should be minimum and 3. voltage between V&Y and V&B should be same U.V&W are primary (Delta) R,Y&B are secondary (Star)
