Usage of string functions in PeopleCode using Java Objects

Here is the code for performing string manipulations in peoplesoft using JavaObjects, i have used the string utilities from "org.apache.commons.lang.StringUtils" which are part of "java.lang.object"



Local JavaObject &original = CreateJavaObject("java.lang.String", "Hello World!");

Local JavaObject &jClass = GetJavaClass("org.apache.commons.lang.StringUtils");

Local string &reversed = &jClass.reverse(&original);

Local string &caps = &jClass.upperCase(&original);

Local string &lower = &jClass.lowerCase(&original);

Local string &index_of = &jClass.indexOf(&original, "o");

Local string &removed = &jClass.remove(&original, "o");

Local string &substr = &jClass.substring(&original, 3);

MessageBox(0, "", 0, 0, "This is original " | ": " | &original.toString());

MessageBox(0, "", 0, 0, "The length of the string is " | ": " | &original.length());

MessageBox(0, "", 0, 0, "This is reversed " | ": " | &reversed);

MessageBox(0, "", 0, 0, "This is capitalised " | ": " | &caps);

MessageBox(0, "", 0, 0, "This is lower " | ": " | &lower);

Rem MessageBox(0, "", 0, 0, "This is splitted " | ": " | &splitted);

MessageBox(0, "", 0, 0, "The index of " | "o is" | ": " | &index_of);

Running the above program in the Application Engine would produce the following output:
