Convert String to boolean using Boolean.parseBoolean() method

The first solution, we can use the Boolean.parseBoolean() method to parse a String value into boolean as following Java example program.

StringToBooleanExample1.java 

public class StringToBooleanExample1 {
    public static void main(String... args) {
        String stringValue1 = "true";
        String stringValue2 = "false";

        boolean booleanValue1 = Boolean.parseBoolean(stringValue1);
        boolean booleanValue2 = Boolean.parseBoolean(stringValue2);

        System.out.println(booleanValue1);
        System.out.println(booleanValue2);
    }
}
The output as below. 
true
false

Convert String to boolean using Boolean.valueOf() method

The second solution, we can use the Boolean.valueOf() method to instantiate a boolean value from a String as below Java code.

StringToBooleanExample2.java 

public class StringToBooleanExample2 {
    public static void main(String... args) {
        String stringValue1 = "true";
        String stringValue2 = "false";

        boolean booleanValue1 = Boolean.valueOf(stringValue1);
        boolean booleanValue2 = Boolean.valueOf(stringValue2);

        System.out.println(booleanValue1);
        System.out.println(booleanValue2);
    }
}
The output as below. 
true
false

Happy Coding 😊
