Question

Write a java program that solves the following problem The program will read user input of compound propositional logic statement and give truth table for each proposition and the final proposition
For example (p or q) and r so it will print first p or q truth table and then it will print truth table for (p or q) and r Write a java program that solves the following problem The program will read user input of compound propositional logic statement and give truth table for each proposition and the final proposition

Explanation / Answer

UPDATED PROGRAM

import java.io.*;

class TTDemo1
{
private static void printTruthTable(int n) {
int rows = (int) Math.pow(2,n);

for (int i=0; i<rows; i++) {
for (int j=n-1; j>=0; j--) {
System.out.print((i/(int) Math.pow(2, j))%2+" ");
}
System.out.println();
}
}
public static void main(String args[])
{
boolean p,q,r; // Declare p,q and r boolean variables
  
System.out.print("========================================================= ");

System.out.println("p q r (p OR q) ((p OR q) AND r) ");
System.out.print("========================================================= ");

p = false; // Initially set p=false

do{
q=false; // Initially set q=false

do {

r= false; // Initially set r=false

do {

System.out.println(p + " " + q + " " + r + " " + (p || q)+" "+ ((p||q)&&r)); // Display resultant truth table

r = !r; // set not r

} while (r); // r is true
  

q = !q; // set not q
}while(q); // q is true

p=!p; // set not p
} while (p); // p is true
System.out.print("========================================================= ");
}
}

F:>javac TTDemo1.java

F:>java TTDemo1
=========================================================
p q r (p OR q) ((p OR q) AND r)

=========================================================
false false false false false
false false true false false
false true false true false
false true true true true
true false false true false
true false true true true
true true false true false
true true true true true
=========================================================
