Relational operator is used for single condition check. If you want to check multiple condition. Than you requires logical operator. These logical operator are && logical And, || logical OR and ! Logical Not. It returns only  boolean value.

package com.devmanuals;

public class LogicalOperator {
	int a = 10, b = 10, c = 10;
	boolean bool = false, bool1 = true;

	public void logicalAND() {
		if ((a == b) && (a == c)) {
			System.out.println("a is equal to b and c.");
		} else {
			System.out.println("a is not equal to b and c.");
		}
	}
	public void logicalOR() {
		System.out.println("bool || bool1 : " + (bool || bool1));
	}
	public void logicalNot() {
		System.out.println("bool1!= true : " + (bool1 != true));
	}
	public static void main(String[] args) {
		LogicalOperator obLogicalOperator = new LogicalOperator();
		obLogicalOperator.logicalAND();
		obLogicalOperator.logicalOR();
		obLogicalOperator.logicalNot();
	}
}
