Statements are similar to sentences in the English language. A sentence forms a complete idea which can include one or more clauses. Likewise, a statement in Java forms a complete command to be executed and can include one or more expressions.

In simpler terms, a Java statement is just an instruction that explains what should happen.

Types of Java Statements

There are three main groups that encompass the different kinds of statements in Java:

  • Expression statements change values of variables, call methods, and create objects.
  • Declaration statements declare variables.
  • Control flow statements determine the order that statements are executed. Typically, they're understood from top to bottom. However, with control flow statements, that order can be interrupted to implement branching or looping so that the Java program can run particular sections of code based on certain conditions.

Examples of Java Statements

 //declaration statement
 int number;
 //expression statement
 number = 4;
 //control flow statement
 if (number < 10 )
   //expression statement
   System.out.println(number + " is less than ten");
