Java Program Converts Boolean (boolean) Variable to String (string)

Comprehensive Java Examples

In this program, we will learn how to convert a boolean type variable to a string in Java.

To understand this example, you should be familiar with the followingJava ProgrammingTopic:

• Java Variables and (Primitive) Data Types

• Java String

We can also use the toString() method of the Boolean class to convert a boolean variable to a string. For example,1Using valueOf() to convert a boolean value to a string

Example
　　class Main {
　　　　//public static void main(String[] args) {
　　　　= true;1　Creating a boolean variable
　　　　= true;2　boolean booleanValue
　　　　//= false;
　　　　//Using valueOf()
　　　　String stringValue1　= String.valueOf(booleanValue1);
　　　　String stringValue2　= String.valueOf(booleanValue2);
　　　　System.out.println(stringValue1);　　　　//　true
　　　　System.out.println(stringValue2);　　　　//　true
　　}
}

In the above example, we use the valueOf() method of the String class to convert a boolean variable to a string.

We can also use the toString() method of the Boolean class to convert a boolean variable to a string. For example,2：使用toString()将布尔值转换为字符串

: Using toString() to convert a boolean value to a string

Example
　　class Main {
　　　　//public static void main(String[] args) {
　　　　= true;1　Creating a boolean variable
　　　　= true;2　boolean booleanValue
　　　　//　= false;
　　　　//　Using toString() to convert a boolean value to a string
　　　　String stringValue1　= Boolean.toString(booleanValue1);
　　　　String stringValue2　= Boolean.toString(booleanValue2);
　　　　System.out.println(stringValue1);　　　　//　true
　　　　System.out.println(stringValue2);　　　　//　true
　　}
}

In the above example, the toString() method of the Boolean class converts a boolean variable to a string. Here, Boolean is a wrapper class. For more information, please visitJava Wrapper Class.
