Graphical examples of equalsIgnoreCase method in java

This method compares one string with another string, ignoring case during the comparison. If the parameter is not null and the two Strings are equal (ignoring case), then true is returned; otherwise false is returned.

Syntax

equalsIgnoreCase(String anotherString)

anotherString: anotherString is the string object specified for comparison.

Example Use the equalsIgnoreCase () function to compare whether the string strCom1 and the string strCom2 are equal.

String strCom1 = "MN";
String strCom2 = "mn";
boolean strB = strCom1.equalsIgnoreCase(strCom2);

Typical applications The equals method and the equalsIgnoreCase method are both very widely used methods. The difference between the two is that the equals method is strictly case-sensitive during the comparison process, while the equalsIgnoreCase method is case-sensitive during the comparison process. Case is ignored in the procedure. This example uses two strings that differ only in upper and lower case, and uses these two methods for comparison. The results are shown in Figure 1.3.

The key code of this example is as follows:

public static void main(String[] args) {
  String str1 = "I LIKE JAVA";    //定义字符串
  String str2 = "i like java"; 
  boolean bool1 = str1.equals(str2);   //使用equals方法进行比较
  boolean bool2 = str1.equalsIgnoreCase(str2); //使用equalsIgnoreCase方法进行比较
  System.out.println("使用equals方法进行比较："+bool1); //输出比较结果
  System.out.println("使用equalsIgnoreCase方法进行比较："+bool2);
}
