In this article, we will discuss String comparison with StringBuffer using String’s contentEquals() method
1. String’s contentEquals(StringBuffer sb) method:
- This String method compares the contents of string with supplied/passed StringBuffer
1.1 Method Signature:
public boolean contentEquals(StringBuffer sb);
1.2 Returns:
Returns a boolean value either true or false
- True –> if string matches with StringBuffer
- False –> if string doesn’t matches with StringBuffer
2. Examples on contentEquals() method:
- Below demo program compares String with StringBuffer using String’s contentsEquals() method
StringContentEqualsMethod.java
package in.bench.resources.string.methods;
public class StringContentEqualsMethod {
public static void main(String[] args) {
// String literals
String str1 = "BenchResources.Net";
String str2 = "Oracle.Com";
// StringBuffer
StringBuffer sb1 = new StringBuffer("BenchResources.Net");
// comparing String and StringBuffer
boolean contentEquals1 = str1.contentEquals(sb1);
// printing to console
System.out.println("str1 contentsEqual with sb1 : "
+ contentEquals1);
// again, comparing String and StringBuffer
boolean contentEquals2 = str2.contentEquals(sb1);
// printing to console
System.out.println("str2 contentsEqual with sb1 : "
+ contentEquals2);
}
}
Output:
str1 contentsEqual with sb1 : true
str2 contentsEqual with sb1 : false
Note: There is one variation to this String method which accepts CharSequence as input arguments
Method Signature:
public boolean contentEquals(CharSequence cs);
