Answer 1

String out = Character.toUpperCase(inText.charAt(0)) + inText.substring(1).toLowerCase();

Answer 2

public static void main(String[] args) {
    String str = null;
    String outStr = null;
    Scanner sc = new Scanner(System.in);
    System.out.println("Enter a String: ");
    str = sc.nextLine();
    //c= Character.toUpperCase(str.charAt(0));

    for(int i=0; i< (str.length());i++){

        if(str.charAt(i)==' '){

            outStr= outStr.substring(0,i+1)+str.substring(i+1,i+2).toUpperCase()+str.substring(i+2);

        }else if(i==0){

            outStr=str.substring(0,1).toUpperCase()+str.substring(1);

        }
    }
    System.out.println("STRING::"+outStr);
}
