Description
How to convert String object to boolean primitive in Java.
Example: Complete conversion code
In this example we are converting string to boolean using parseBoolean() method of Boolean class.
class StringToboolean {
public static void main(String[] args) {
// String Objects
String str = "false";
// Case does not matter for conversion
String str2 = "TrUe";
// String to boolean conversion
boolean bvar = Boolean.parseBoolean(str);
boolean bvar2 = Boolean.parseBoolean(str2);
// Displaying boolean values
System.out.println("boolean value of String str is: "+bvar);
System.out.println("boolean value of String str2 is: "+bvar2);
}
}
Output:
boolean value of String str is: false boolean value of String str2 is: true
public static boolean parseBoolean(String s): Parses the string argument as a boolean. The boolean returned represents the value true if the string argument is not null and is equal, ignoring case, to the string “true”.
Example: Boolean.parseBoolean(“True”) returns true.
Example: Boolean.parseBoolean(“yes”) returns false.
