1. Get Character as a String

1.1 Using the Character.toString() Method

@Test
@DisplayName("assertJ_Using the Character.toString() Method")
void getCharAsACharacterToStringAssertJ(){
	String charAtVar2 = Character.toString("abc".charAt(0));
	assertThat(charAtVar2).isEqualTo("a");
}

@Test
@DisplayName("JUnit_Using the Character.toString() Method")
void getCharAsAStringValueOfAndCharacterToStringJUnit(){
	String sample = "abc";
	assertEquals("a", Character.toString(sample.charAt(0)));
}

1.2 Using the String.valueOf() Method

@Test
@DisplayName("assertJ_Using the String.valueOf() Method")
void getCharAsAStringValueOfAssertJ(){
	String charAtVar1 = String.valueOf("abc".charAt(1));
	assertThat(charAtVar1).isEqualTo("b");
}

@Test
@DisplayName("JUnit_Using the String.valueOf() Method")
void getCharAsAStringValueOfAndCharacterToStringJUnit(){
	String sample = "abc";
	assertEquals("b", String.valueOf(sample.charAt(1)));
}
