[Brick Java] Relational Operators

• relational operator
• Relational operators, also known as "comparison operators", are used to compare and determine the size of two variables or constants.
• The results of relational operators are all boolean, that is, either true or false.

• 

• The precedence of relational operators are: >, <, >=, <= have the same precedence and are higher than !=, == which have the same precedence. The precedence of relational operators is higher than that of assignment operators and lower than that of arithmetic operators, and the association direction is left-to-right.
• Relational expressions are often used in the condition of an if construct or in the condition of a loop construct.
• Expressions composed of relational operators are called relational expressions. a > b
• for example

• package demo01;
  
  public class demo4 {
      public static void main(String[] args) {
          int a = 6;
          int b = 3;
          System.out.println(a > b);//true
          System.out.println(a >= b);//true
          System.out.println(a <= b);//false
          System.out.println(a < b);//false
          System.out.println(a == b);//false
          System.out.println(a != b);//true
          boolean p1 = a > b;//true
          System.out.println("p1="+p1);//p1=true
      }
  }
