Java Truth-Table

     

Truth tables are used to determine whether a prepositional expression is true or false for all input values, that are, logically valid. The Truth-Table below shows the functioning of the Boolean logical operators AND (&), OR(|), XOR (^) and NOT (!).

Boolean logical operators AND (&), OR(|), XOR (^) and NOT (!).

  • & - It produces true if both operands are true otherwise produces false.
  • | - It produces false if both operands are false otherwise produces true.
  • ^ - It produces true if both operands are different otherwise produces false.
  • ! - It produces true if both operands are false and produces false if both operands are true.

Here is the code of program:

public class truthtable {  
  public static void main(String[] args) {  
 
  boolean r, s; 
 
  System.out.println"R\tS\tAND\tOR\tXOR\tNOT" )
 
  r = true; s = true
  System.out.print(r + "\t" + s + "\t")
  System.out.print((r&s"\t" (r|s"\t")
  System.out.println((r^s"\t" (!r))
 
  r = true; s = false
  System.out.print(r + "\t" + s + "\t")
  System.out.print((r&s"\t" (r|s"\t")
  System.out.println((r^s"\t" (!r))
 
  r = false; s = true
  System.out.print(r + "\t" + s + "\t")
  System.out.print((r&s"\t" (r|s"\t")
  System.out.println((r^s"\t" (!r))
 
  r = false; s = false
  System.out.print(r + "\t" + s + "\t")
  System.out.print((r&s"\t" (r|s"\t")
  System.out.println((r^s"\t" (!r))
  }  
}

Output of the program:

C:\unique>javac truthtable.java

C:\unique>java truthtable
R  S   AND   OR   XOR   NOT
true  true   true   true  false  false
true  false  false  true   true  false
false   true   false  true   true  true
false   false  false  false  false  true
