The String.valueOf () method converts data from its internal format into a human-readable form.

The Java string valueOf() method converts different types of values into a string. 

Java String valueOf() Method Example

Let's see an example where we are converting all primitives and objects into strings.

public class StringValueOfExample5 {
    public static void main(String[] args) {
        boolean b1=true;
        byte b2=11;
        short sh = 12;
        int i = 13;
        long l = 14L;
        float f = 15.5f;
        double d = 16.5d;
        char chr[]= {
            'j',
            'a',
            'v',
            'a'
        }
        ;
        StringValueOfExample5 obj=new StringValueOfExample5();
        String s1 = String.valueOf(b1);
        String s2 = String.valueOf(b2);
        String s3 = String.valueOf(sh);
        String s4 = String.valueOf(i);
        String s5 = String.valueOf(l);
        String s6 = String.valueOf(f);
        String s7 = String.valueOf(d);
        String s8 = String.valueOf(chr);
        String s9 = String.valueOf(obj);
        System.out.println(s1);
        System.out.println(s2);
        System.out.println(s3);
        System.out.println(s4);
        System.out.println(s5);
        System.out.println(s6);
        System.out.println(s7);
        System.out.println(s8);
        System.out.println(s9);
    }
}

Output:

true 11 12 13 14 15.5 16.5 java StringValueOfExample5@2a139a55
