what is integer.parseint code example

Example 1: parseints(str) java

int decimalExample = Integer.parseInt("20"); 
        int signedPositiveExample = Integer.parseInt("+20"); 
        int signedNegativeExample = Integer.parseInt("-20"); 
        int radixExample = Integer.parseInt("20",16); 
        int stringExample = Integer.parseInt("geeks",29); 
  
        // Uncomment the following code to check 
        // NumberFormatException 
  
        //   String invalidArguments = ""; 
        //   int emptyString = Integer.parseInt(invalidArguments); 
        //   int outOfRangeOfInteger = Integer.parseInt("geeksforgeeks",29); 
        //   int domainOfNumberSystem = Integer.parseInt("geeks",28); 
  
        System.out.println(decimalExample); 
        System.out.println(signedPositiveExample); 
        System.out.println(signedNegativeExample); 
        System.out.println(radixExample); 
        System.out.println(stringExample); 

Output:

Example 2: parseint

// parseInt
parseInt("10");//------------ 10
parseInt("10.00");//--------- 10
parseInt("10.33")//--------- 10
parseInt("34 45 66")//------ 34
parseInt("   60   ")//------ 60
parseInt("40 years")//------ 40
parseInt("He was 40")//----- NaN
parseInt("10", 10)//-------- 10
parseInt("010")//----------- 10
parseInt("10", 8)//--------- 8
parseInt("0x10")//---------- 16
parseInt("10", 16)//-------- 16
// parseFloat
parseFloat("10")//-----------10
parseFloat("10.00")//--------10
parseFloat("10.33")//--------10.33
parseFloat("34 45 66")//-----34
parseFloat(" 60 ")//---------60
parseFloat("40 years")//-----40
parseFloat("He was 40");//----NaN
