Java Sundaresan

Since there was another actor by his birth name of Swaminathan, he briefly considered Chama as a stage name, which was what he was called by Crazy Mohan. He renamed himself as Chaams for the serial Chinna Papa Periya Papa.^[4] He initially acted with comedians like Vadivelu and supported their comedy roles and later bagged larger roles.

His breakthrough role came in the film Arai En 305-il Kadavul as Java Sundaresan, an aspiring software engineer who bags a job due to his knowledge of Java. He constantly climbs the social ladder due to his high paying job.^[2] In the year 2009, a film named Palaivana Solai was released which was a remake version of the same film released in 1981 where a love story of five friends woven around one simple girl received critics appreciation. Chaams played the lead role as one of the five friends.

Chaams garnered acclaim for his role in Payanam (2011) as a fan of "Shining Star" Chandrakanth (inspired by "Super Star" Rajinikanth). Rediff stated that a "special mention must be made of Chaams" as he provided "excellent comic relief".^[5] The Hindu stated that "Chaams as the doting fan whose blinkers fall off" is "a riot".^[6] Similarly in the year 2013, another film Onbadhule Guru was released, where he played the role of a disgruntled married man who wanted to go back to his bachelor days along with his other friends. The film needed all leading actors to do comedy as per the script. He played one of the leads in the film Thittam Poattu Thirudura Kootam (2019).^[7]

In 2021, Chaams played the lead role in the film Operation JuJuPi as a serious man.^[8] In 2025, he changed his stage name from Chaams to Java Sundaresan as many meme creators were using the latter name.^[2]
