The do Keyword   

     

Keywords are special symbols in the Java programming language, which are reserved for a Java program.

The do is a Java keyword, that may not be used as identifiers i.e. you cannot declare a variable or class with this name in your Java program. This keyword is used in control statement to declare a loop. It provides a repetitive task as long as the condition specified with the while keyword is true; then it exits from the loop when the specified condition is founded as false.

The syntax of do loop is written as: 

do{    statement;  } while (condition);

  The do loop iterates a block of statements. For example:

do {   i++; } while ( i < maxNum );

 The do loop block is always executed once whether the condition specified with the while keyword is true or false.
