Exercise 17-3: Find the duplicates in the following array of Strings.
String words = { "I","love " , " coffee " , " I " , " love " , " tea " } ;
for (int i = 0; i < _______________; i + + ) {
}
for (int j = __; j < _______________; j + + ) {
}
if (___________________) {
}
println(____________ + " is a duplicate. " );
One other feature of String objects is concatenation, joining two Strings together. Strings are joined with
the “ � ” operator. Th e plus operator ( � ), of course, usually means add in the case of numbers. When used
with Strings , it means join .
String helloworld = " Hello " + " World " ;
Variables can also be brought into a String using concatenation.
int x = 10;
String message = " The value of x is: " + x;
We saw a good example of this in Chapter 15 when loading an array of images with numbered fi lenames.
Exercise 17-4: Concatenate a String from the variables given that outputs the following
message.
Th at rectangle is 10 pixels wide, 12 pixels tall and sitting right at (100,100).
float w = 10;
float h = 12;
float x = 100;
float y = 100;
String message = ____________________________________;
println(message);
