I need help writing a program to count the number of equal pairs of words in a string. The program should be in Java.

For example:

If the input string text is: spring java spring spring spring javascript java jboss jboss tomcat jboss

Then the program must output:

spring: 6 combo-pairs (0,2) (0,3) (0,4) (2,3) (2,4) (3,4) AND 2 next-to-pairs (2,3) (3,4)

java: 1 combo-pair (1,6) AND 0 next-to-pairs

javascript: 0 combo-pairs AND 0 next-to-pairs

jboss: 3 combo-pairs (7,8) (7,10) (8,10) AND 1 next-to-pair (7,8)

tomcat: 0 combo-pairs AND 0 next-to-pairs
