A more thorough explanation:

Definition: The bar refers to all the lawyers who are qualified to practice law in a specific court or jurisdiction. Each state has its own requirements for admitting a person into their jurisdiction's bar. Generally, a person must meet a state's admissions requirements, such as earning a Juris Doctor degree, passing a professional responsibility examination, passing the bar examination, and having their character and fitness evaluated. Judges are also part of the bar, but they are often referred to as "the bench," while lawyers representing clients in court are referred to as "the bar."

Example: John passed the bar exam and was admitted to the New York State Bar. He can now practice law in New York.

Explanation: This example illustrates how a person can become a member of the bar by meeting a state's admissions requirements and passing the bar exam. John is now qualified to practice law in New York.
