Program:

            /* ............... START ............... */
                
public class JavaRegionMatchExample {
	public static void main(String args[]) {
		String str1 = new String("Hello, How are you");
		String str2 = new String("How");
		String str3 = new String("HOW");

		System.out.print("Result of Test1: ");
		System.out.println(str1.regionMatches(7, str2, 0, 3));

		System.out.print("Result of Test2: ");
		System.out.println(str1.regionMatches(7, str3, 0, 3));

		System.out.print("Result of Test3: ");
		System.out.println(str1.regionMatches(true, 7, str3, 0, 3));
	}
}
                /* ............... END ............... */
        

Output

Result of Test1: true
Result of Test2: false
Result of Test3: true

Notes:

  • regionMatches has two variants which can be used to test if two string regions are equal.
  • Syntax : public boolean regionMatches(int toffset, String other, int ooffset, int len).
  • ignoreCase– if true, ignore case when comparing characters.
  • toffset – the starting offset of the subregion in this string.
  • other – the string argument.
  • ooffset – the starting offset of the subregion in the string argument.
  • len – the number of characters to compare.
