Java puzzle Help needed

Write a Program which takes ‘n’ non-zero Integer arguments where n>3.
You need to use n-1 arguments in the same order to have the result as the nth argument by applying any of the arithmetic operators [ + , - , * , / ].
Assume all the operators will have same precedence.

Example 1:
Given n = 5 numbers are
1 2 3 4 20
Solution has to be provided in such a way that output should be as below
1 * 2 + 3 * 4 = 20

Example 2:
Given n = 3 numbers are
10 2 5
Solution has to be provided in such a way that output should be as below
10 / 2 = 5
