class

{
public
public static
void
main
(
String
[]
argv
) {
System
.
out
.
println
(
"Java Strings in action:"
);
// System.out.println("An alarm or alert: \a"); // not supported
System
.
out
.
println
(
"An alarm entered in Octal: \007"
);
System
.
out
.
println
(
"A tab key: \t(what comes after)"
);
System
.
out
.
println
(
"A newline: \n(what comes after)"
);
System
.
out
.
println
(
"A UniCode character: \u0207"
);
System
.
out
.
println
(
"A backslash character: \\"
);
static
void
}
}
If you have a lot of non-ASCII characters to enter, you may wish to consider using Java's in-
put methods, discussed briefly in the JDK online documentation.
