LANGUAGE: JAVA CHALLENGE: Given a String variable named sentence that has been initialized, write an expression whose value is the number of characters in the String referred to by sentence.

LANGUAGE: JAVA CHALLENGE: Write an expression that concatenates the String variable suffix onto the end of the String variable prefix.

LANGUAGE: JAVA CHALLENGE: Given three String variables that have been declared and given values, gold, silver, and bronze, write an expression whose value is the values of each these variables joined by a newline character. So if gold, silver, and bronze, had the values  “Arakawa”, “Cohen”, and “Slutskaya”, the expression, if it were printed would have the names “Arakawa”, “Cohen”, and “Slutskaya”…

LANGUAGE: JAVA CHALLENGE: Given a String variable word, write a String  expression that parenthesizes the value of word. So, if word contains “sadly”, the value of the expression would be the String “(sadly)”

LANGUAGE: JAVA CHALLENGE: Given three String variables  that have been declared  and given values, firstName, middleName, and lastName, write an expression whose value  is the values  of each these variables  joined by a single space. So if firstName, middleName, and lastName, had the values  “Big”, “Bill”, and “Broonzy”, the expression’s value  would be “Big Bill Broonzy”. Alternatively, if…

LANGUAGE: JAVA CHALLENGE: Given four int variables that have been declared and given values, octet1, octet2, octet3, and octet4, write a String  expression whose value is the String equivalent of each these variables joined by a single period (.) So if octet1, octet2, octet3, and octet4, had the values 129, 42, 26, and 212 the expression’s value would be “129.42.26.212”. Alternatively, if octet1,…

LANGUAGE: JAVA CHALLENGE: Given three int variables that have been declared and given values, areaCode, exchange, and lastFour, write a String expression whose value is the String equivalent of each these variables  joined by a single hyphen (-) So if areaCode, exchange, and lastFour, had the values  800, 555, and 1212, the expression’s value would be “800-555-1212”. Alternatively, if…

LANGUAGE: JAVA CHALLENGE: Given a String variable address, write a String expression consisting of the string “http://” concatenated with the variable’s String value. So, if the variable refers to “www.turingscraft.com”, the value of the expression would be “http://www.turingscraft.com”.

LANGUAGE: JAVA CHALLENGE: Declare a String variable named oneSpace, and initialize it to a String consisting of a single space.
