To input a string just use: keyboard.nextString()
To output its length it'd be like:

str1 = keyboard.nextString();
str1.length();

To output the character at an index, use charAt(i)

str1.charAt(i)

gives you the value at the index "i"

And to output the first occurrence of a char in str1, use indexOf(char)

str1.indexOf(char)

gives you the index of first occurrence of the character "char"
