Java String.valueOf()

The method valueOf() has several overloads that accept one parameter of different types and convert them to a String. Examples include boolean, char, char array, double, int and long. We can also convert a part of a char array to a String by passing:

• offset – the index of the character to start converting from
• count – the number of characters to convert

Available Signatures

public static String valueOf(boolean b)
public static String valueOf(char c)
public static String valueOf(char[] data)
public static String valueOf(char[] data, int offset, int count)
public static String valueOf(double d)
public static String valueOf(float f)
public static String valueOf(int i)
public static String valueOf(long l)
public static String valueOf(Object obj)

@Test
public void whenCallValueOf_thenCorrect() {
    long l = 200L;
    
    assertEquals("200", String.valueOf(l));
}
