这时可以使用replaceAll方法去掉空格后再比较。 Stringstr3="Hello World";Stringstr4="HelloWorld";if(str3.replaceAll("\\s","").equals(str4.replaceAll("\\s","")){System.out.println("Two strings are equal ignoring whitespace.");}else{System.out.println("Two strings are not equal ignoring whi...
Hence, str1.equals(str2) returns true. str1 and str3 are not equal. Hence, str1.equals(str3) and str3.equals(str1) returns false. Example 2: Check if Two Strings are Equal class Main { public static void main(String[] args) { String str1 = "Learn Python"; String str2 = "...

Two strings are equal only if they contain the same sequence of characters. Trailing blanks are significant; for example, the strings 'abc' and 'abc ' are not equal.Two entities of the same abstract schema type are equal only if their primary keys have the same value. Table 22–9 shows...

It checks if str3 is equal to null and prints the appropriate message. Output: When you run the code, it produces the following output: str1 is null or empty. str2 is null or empty. str3 is not null or empty. The output confirms that str1 and str2 are null or empty strings,...
